Detailed Description
To make the objects, technical solutions and advantages of the present specification more apparent, the present specification is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.

As described in the background section, the semiconductor laser and the Semiconductor Optical Amplifier (SOA) work in an excitation mode, and light is emitted in a transition manner between energy bands by using a semiconductor substance (i.e., electrons), and two parallel mirror surfaces are formed on a cleavage plane of a semiconductor crystal as mirrors to form a resonant cavity, so that light is oscillated and fed back to generate light radiation, which is amplified and output as laser light. The semiconductor optical amplifier is a device using a light emitting device-semiconductor laser structure as an amplifying device, and simultaneously utilizes nonlinear characteristics of SOA, namely parametric mixing, cross gain modulation and cross phase modulation, so that wavelength conversion can be realized. The semiconductor laser is reasonably utilized as pump light, the amplification characteristic and the nonlinear characteristic of the SOA are the key of the tunable all-optical wavelength conversion system, and meanwhile, the integration and the tunability are two crucial indexes. As a wavelength converter, the reliability and response of the tunable system is crucial. The method comprises the steps of stabilizing and high-speed output wavelength of the laser, solving the drift phenomenon in the wavelength switching process, the working efficiency of the SOA and the like. In the prior art, the design of a driving and controlling system matched with a semiconductor laser and an SOA cannot ensure that wavelength conversion achieves stable and efficient switching efficiency. In addition, in the transmission process of different wavelengths, the gain characteristics of the SOA are different, and current driving of different degrees is required.
In combination with the above practical situation, the embodiments of the present disclosure provide an all-optical wavelength conversion scheme, which utilizes serial-to-parallel conversion serial asynchronous communication characteristics to reliably control and monitor services of a tunable optical wavelength conversion system. When the wavelength is switched, the semiconductor laser and the semiconductor optical amplifier related to the wavelength switching are controlled by using the data information acquired in a serial-parallel conversion mode, the information change response of the wavelength is timely performed, the serial-parallel conversion interface is reasonably used for communication control, and the stable and efficient switching efficiency is achieved.
Referring to fig. 1, a schematic flow chart of an all-optical wavelength conversion method according to an embodiment of the present disclosure is shown, which specifically includes the following steps:
The step aims to acquire initial channel data, and determine whether wavelength switching is required according to the wavelength of the initial channel data, so as to determine whether the scheme mentioned in this embodiment needs to be executed. The channel refers to a communication channel, and is a medium for signal transmission. The channel data is data transmitted in a channel, and generally refers to light wave data in an optical fiber in this embodiment, and further, the wavelength information generally refers to a wavelength of a light wave, and the wavelength (wavelength) refers to a distance that the wave travels in one vibration period. I.e. the distance between two adjacent points whose vibration phases differ by 2 pi, along the direction of propagation of the wave.
Then, judging whether to perform wavelength switching on the channel data according to the wavelength information, wherein the determining mode can be that whether the wavelengths of the channel data are consistent or not is determined according to a set wavelength value, and if the wavelengths are inconsistent, the wavelength switching is performed; whether wavelength switching is needed or not can be determined according to the wavelength transmitting/receiving format between the transmitting side and the receiving side of the channel data; it is also possible to determine whether wavelength switching is required or not, etc., based on the propagation distance after the channel data, etc.
And 102, responding to the channel data needing wavelength switching, acquiring data information in the wavelength information in a serial-parallel conversion mode, performing wavelength switching control through the data information, and generating tuned wavelength data after switching.
The step aims to acquire data information by using serial-to-parallel conversion serial asynchronous communication characteristics so that the embodiment can respond to the information change of the wavelength in time, and then realize wavelength switching control by using the data information to control a laser, an optical amplifier and the like so as to generate channel data after the wavelength is changed. The serial-to-parallel conversion mode is a mode for converting transmitted data between serial communication and parallel communication, and may include a UART (Universal Asynchronous Receiver/Transmitter), a USART (Universal Synchronous/Asynchronous Receiver/Transmitter), and the like. Then, control information such as voltage, current, temperature, etc. at the time of wavelength switching is determined by the data information. And finally, carrying out wavelength switching on the channel data according to the data information to convert the optical wave from one wavelength to another wavelength and generate final tuned wavelength data.
Optionally, the serial asynchronous communication characteristic of the UART interface is utilized, so that the service of the tunable optical wavelength conversion system can be reliably controlled and monitored. In a specific application scenario, when wavelength switching is performed, the laser serves as a pumping light source, the SOA serves as an amplifying and switching device, wavelength information change needs to be responded to in time, a UART interface is reasonably utilized for communication control, and stable and efficient switching efficiency can be achieved. In addition, in the transmission process of different wavelengths, the gain characteristics of the SOA are different, current driving of different degrees is required, and the switching can be performed more stably by using the UART. Among them, a Universal Asynchronous Receiver/Transmitter (UART) is a serial Asynchronous Receiver/Transmitter protocol, and is widely used. The UART works by transmitting bits of data bit by bit. In the UART communication protocol, the high level of the status bit on the signal line represents '1' and the low level represents '0'. In UART communication, two UARTs communicate directly with each other. The transmitting UART converts parallel data from a control device such as a CPU into serial form and transmits it serially to the receiving UART, which then converts the serial data back to the parallel data of the receiving device. Only two wires are required to transmit data between two UARTs. Data flows from the Tx pin of the transmitting UART to the Rx pin of the receiving UART. In UART communication, two UARTs communicate directly with each other. The transmitting UART converts parallel data from a control device such as a CPU into serial form and transmits it serially to the receiving UART, which then converts the serial data back to the parallel data of the receiving device. Only two wires are required to transmit data between two UARTs. Data flows from the Tx pin of the transmitting UART to the Rx pin of the receiving UART.
And 103, outputting the tuning wavelength data.
This step is intended to output the tuned wavelength data (i.e., the wavelength adjusted channel data) for transmission or other processing. If the tuned wavelength data needs to be further processed, the specific output mode of the tuned wavelength data can be flexibly selected according to different application scenes and implementation requirements.
For example, for an application scenario in which the method of the present embodiment is executed on a single device, the tuned wavelength data may be directly output in a displayed manner on a display means (display, projector, etc.) of the current device, so that an operator of the current device can directly see the content of the tuned wavelength data from the display means.
For another example, for an application scenario executed on a system composed of multiple devices by the method of this embodiment, the tuning wavelength data may be sent to other preset devices as receivers in the system through any data communication manner (e.g., wired connection, NFC, bluetooth, wifi, cellular mobile network, etc.), so that the preset devices receiving the tuning wavelength data may perform subsequent processing on the tuning wavelength data. Optionally, the preset device may be a preset server, the server is generally disposed at a cloud end, and is used as a data processing and storage center, and the server can store and distribute the tuning wavelength data; the receiver of the distribution is a terminal device, and the holder or operator of the terminal device may be a controller of the current optical fiber adjustment, other units, departments, individuals, and the like, which need to manage or control the optical fiber data.
For another example, for an application scenario executed on a system composed of multiple devices, the method of this embodiment may directly send the tuning wavelength data to a preset terminal device through any data communication manner, where the terminal device may be one or more of the foregoing paragraphs.

One or more embodiments of the present disclosure utilize serial-to-parallel conversion for serial asynchronous communication to reliably control and monitor the traffic of tunable optical wavelength conversion systems. When the wavelength is switched, the semiconductor laser and the semiconductor optical amplifier related to the wavelength switching are controlled by using the data information acquired in a serial-parallel conversion mode, the information change response of the wavelength is timely performed, and the communication control is performed by using the serial-parallel conversion interface, so that the stable and efficient switching efficiency is achieved.

The method of the embodiment of the disclosure can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices.

In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In some application scenarios, in order to accurately complete wavelength switching control, wavelength switching can be flexibly adjusted according to temperature information in the switching process. The controlling of wavelength switching through the data information includes: controlling laser generation and laser amplification through the data information to complete the wavelength switching control; and detecting the temperature variation in the laser generation and laser amplification processes, and when the temperature variation exceeds a preset threshold, carrying out temperature regulation and control on the laser generation and laser amplification according to the temperature variation.
In the laser generation and laser amplification, a mode of wavelength switching is used, in the wavelength switching process, light is generated by a laser generation device, and the wavelength of the generated light is controlled by a laser amplification device to form a qualified light wave. Of course, the optical wave of the original channel data may also be adjusted directly, but this adjustment may affect the carried data. In a specific application scenario, amplification of light is typically performed by an SOA. Although the SOA has the advantages of simple structure, small volume, capability of fully utilizing the existing semiconductor laser technology, mature manufacturing process, low cost, long service life, low power consumption and the like, the SOA is easily influenced by the environmental temperature and has poor stability, so that the temperature variation in the wavelength switching process needs to be monitored and regulated in real time, and the wavelength switching can be stably completed.
In some application scenarios, the transmission is performed in order to ensure that the temperature variation is stable and efficient. And the temperature variation carries out data transmission in a serial-parallel conversion mode.
The serial-to-parallel conversion mode is generally a UART mode, that is, transmission is performed through a UART interface.
In some application scenarios, wavelength switching is required in order to accurately control. The determining the wavelength information of the channel data and judging whether the channel data needs to be subjected to wavelength switching according to the wavelength information comprises the following steps: and analyzing the wavelength information, determining a control signal of the wavelength information, and judging whether the channel data needs to be subjected to wavelength switching according to the control signal.

In some application scenarios, the serial-to-parallel conversion is specifically performed by a universal asynchronous receiver transmitter.
In some application scenarios, the wavelength information includes: start information, type information, data information, address information, check information, and/or stop information.
Wherein the start information and the stop information are used for marking the start and the end of the communication; the type information indicates a specific type of the channel data, e.g., whether it belongs to a control signal or a data signal, etc.; the data information is used for recording specific control data for wavelength switching; the address information is used for recording a sender and a receiver of the data; the verification information is used to verify the integrity of the data.

After determining the wavelength information of the channel data, the method further includes: according to the verification information, integrity determination is carried out on the channel data; and responding to the complete channel data, and continuously executing the judgment of whether the channel data needs to be subjected to wavelength switching according to the wavelength information.
In a specific application scenario, as shown in fig. 2, a schematic diagram of a framework of an all-optical wavelength conversion system is shown. In the system, the wavelength conversion mainly comprises a wavelength management module, an SOA driving module, a laser and an SOA. The method mainly can realize the exchange function of an electric domain and an optical domain of channelized data, is subdivided into wavelength management of the channelized data, control of a laser and SOA drive, and optical conversion output.
The interface between the wavelength management module and the driving module is a UART communication interface, and the host is used for routing and wavelength-related information processing, so that information forwarding between the management module and the driving module is realized, and wavelength data management and monitoring signals are provided for the driving module.
Fig. 3 is a schematic diagram of a specific working flow of the all-optical wavelength conversion system. Wherein, the step 1: the channel data enters a wavelength management module and wavelength information is analyzed. Step 2: the management module analyzes the control signal in the UART communication protocol, judges whether the wavelength needs to be changed, if so, performs wavelength switching, and then enters step 3, and if not, enters step 6. And step 3: and transmitting information data needing wavelength switching through the UART port. And 4, step 4: the SOA driving module and the laser driving module read information data by utilizing the UART port. And 5: the SOA driving module and the laser driving module analyze the information data and carry out current driving, temperature control and the like on the SOA and the laser. Step 6: and (3) monitoring the temperature of the laser and the SOA in real time by the driving module, if the temperature changes to a certain degree, sending data through the UART interface, and entering the step 3. And 7: outputting a stable tuned wavelength.
