Description
Technical Field
The invention relates to the field of photon integrated chaotic lasers, in particular to an integrated chaotic signal generator based on a micro-ring and a Y-shaped waveguide structure, which is suitable for large-scale integrated chips in the fields of chaotic secret communication and the like.
Background
The chaotic laser has the characteristics of noise-like, wide frequency spectrum and the like, and is widely applied to the fields of optical fiber sensing, secret communication and the like. The DFB laser is used as one of B lasers, is easy to be interfered by the outside and is unstable in output, and is a main device for generating chaotic laser at present.
Currently, there are three main ways of obtaining chaotic lasers: optical feedback, optical injection, and electro-optical feedback. The optical feedback method is widely used because of its simple structure. However, the chaos generated by the optical feedback contains periodic information, which reduces the security of the chaotic secret communication. In addition, the chaotic power spectrum generated by the optical feedback structure is uneven, and the optical feedback structure has obvious relaxation oscillation characteristics. This also limits the application of chaotic lasers.
In view of the above problems, researchers have proposed various schemes for generating broadband non-delayed chaotic light. The use of chirped fiber gratings by the university of Tai Prime university Wang Anbang et al effectively suppresses the chaotic delay of common optical feedback chaos [ Optics Express, 25 (10): 10911, 2017]. The method of double-way phase modulation optical feedback adopted by the university of vinca Feng Yuling and the like suppresses chaotic delay information and simultaneously enhances chaotic bandwidth [ Acta PhysicaSinica, 67 (14): 140501, 2018]. In addition to the scheme of improving the feedback scheme, researchers have proposed a scheme of post-processing the already generated optical feedback chaos. The hong Kong university of City Chen Shijun et al uses chaotic light to inject into a single mode fiber to enhance bandwidth while suppressing delay [ Optics letters, 43 (19): 4751-4754, 2018]. However, the implementation method of the scheme is complex and is not beneficial to actual production. The principals university Wang Anbang et al propose to enhance the chaotic bandwidth and suppress the delay characteristics by using the chaotic laser heterodyne method and the delay self-interference method [ IEEE Journal of Selected Topics in Quantum Electronics, 21 (6) [ 1800710,2015] [ Optics Express, 21 (7) [ 8701-8710, 2013]. Both of these schemes are easy to implement, but are built using discrete devices and require detection with a balanced detector. The system structure is larger, and is not beneficial to integration.

Further, the integrated chaotic signal generator based on the micro-ring and the Y-shaped waveguide structure of the embodiment further comprises silicon-based SiO 2 The first DFB chip 11, the second DFB chip 12, the first feedback waveguide 21, the second feedback waveguide 22, the first transmission waveguide 41, the second transmission waveguide 42, the first micro-ring waveguide 51, the second micro-ring waveguide 52 and the Y-shaped waveguide 6 are all provided withIs placed on said substrate 7. In this embodiment, the chaotic signal will be output from the right side end face of the Y-shaped waveguide 6. In this embodiment, all waveguides are silicon-based passive optical waveguides, and are fabricated by a growth etching method.
Specifically, in this embodiment, the interval between the first DFB chip 11 and the second DFB chip 12 is 26 μm to 30 μm.
Specifically, in this embodiment, the free emission wavelength of the first DFB chip 11 and the second DFB chip 12 is 1550nm, and the first light-emitting end face and the second light-emitting end face are natural dissociation surfaces.
Specifically, in the present embodiment, the length of the first feedback waveguide 21 is 2 times or more that of the first DFB chip 11; the length of the second feedback waveguide 22 is 2 times or more of the second DFB chip 21, and the feedback ratio of the first DFB chip 11 and the second DFB chip 21 is 0.08 to 0.2.
Specifically, in the present embodiment, the lengths of the first transmission waveguide 41 and the second transmission waveguide 42 are each 15 μm or more.
Specifically, in this embodiment, the radii of the first micro-ring waveguide 51 and the second micro-ring waveguide 52 are 5-7 μm. The minimum distance between the first transmission waveguide 41, the first micro-ring waveguide 51, the second micro-ring waveguide 52 and the second transmission waveguide 42 is less than or equal to 0.1 μm.

The two paths of light enter the first and second micro-ring waveguides 51 and 52, respectively, through coupling points a and c, respectively, as shown in fig. 2. During transmission, the two light paths meet and interfere in the coupling point b. Then, the first path of chaotic light propagates to the coupling point c, interferes with the chaotic light emitted from the second DFB chip 12 at the next moment, and is coupled into the second transmission waveguide. And the second path of light propagates to the coupling point a and interferes with the chaotic light emitted by the first DFB chip 11 at the next moment and is coupled into the first transmission waveguide. And then the two paths of light are transmitted to the Y-shaped waveguide to interfere again, and one path of light is synthesized to output.
The interference principle of the invention is as follows: let the electric fields of two chaotic lights be respectively expressed as E 1 (t) and E 2 (t). Wherein,,。A 1 、φ 1 respectively representing the amplitude and phase of the first light path. A is that 2 、φ 2 The amplitude and phase of the second light are shown, respectively. Omega 1 、ω 2 Respectively representing the static angular frequencies of the first path of optical electric field and the second path of optical electric field. The expression of the light intensity after the interference of the two beams is as follows:
；（1）
because the two chaotic lights are independently generated, the light field amplitude A of the two chaotic lights 1 、A 2 Is independent and randomly changed with time. Therefore, through non-resonance interference, the periodic information of the light field intensity of the original chaotic light can be eliminated theoretically, and the chaotic time delay information is further suppressed. In addition, the two chaotic lights have no constant phase difference. In the interference process, the phase oscillation of the two chaotic lights is converted into intensity oscillation, which can enhance the bandwidth of the chaotic power spectrum, improve the flatness and further inhibit the time delay characteristic of the original chaotic lights.
In specific implementation, two DFB laser chips are respectively fixed on SiO 2 The distance between the upper part and the lower part on the left side of the substrate is 26-30 mu m. The two ends of the two DFB chips are not subjected to film plating treatment and are natural dissociation surfaces, and optical signals can be output from the two sides. The parameters of the first DFB chip 11 and the second DFB chip 12 may be mismatched, but it is necessary to ensure that the free emission wavelengths of both lasers are around 1550 nm. The left sides of the two DFB chips are connected with the feedback waveguide 2, and the right sides are connected with the transmission waveguide 3. The lengths of the first feedback waveguide 21 and the second feedback waveguide 22 are different and do not have a multiple relationship, and it is necessary to ensure that both are not smaller than the corresponding lengthsThe length of the laser cavity is 2 times that of the first feedback waveguide 21, i.e., the length of the first feedback waveguide is not less than 2 times that of the first DFB chip 11, and the length of the second feedback waveguide 22 is not less than 2 times that of the second DFB chip 12. This ensures that the feedback light effectively perturbs the DFB chip and causes it to be chaotic. The lengths of the first transmission waveguide 41 and the second transmission waveguide 42 may be different, but it should be ensured that neither is less than 15 μm. The left end faces of the first feedback waveguide 21 and the second feedback waveguide 22 are plated with a reflection enhancing film, and the feedback rate of the end faces is adjusted according to the actual implementation process so as to ensure that the feedback rates of the two lasers are 0.08-0.2. The feedback rate is defined as the ratio of the optical power fed back to the DFB chip through the feedback waveguide to the optical power freely emitted by the DFB chip. The reflectances of the second end surfaces of the first feedback waveguide 21 and the second feedback waveguide 22 may be different, and the feedback coefficients of the first DFB chip 11 and the second DFB chip 12 may be different. The first and second micro-ring waveguides 51 and 52 are located between the first and second transmission waveguides 41 and 42. The radius of the two micro-ring waveguides is 5-7 μm. The radii of the first and second micro-ring waveguides 51 and 52 may be different. The distance between the two micro-rings and the straight waveguide is less than or equal to 0.1 mu m. The two branches of the Y-waveguide 6 are connected to two transmission waveguides, respectively. The chaotic signal is output from the right side of the Y-shaped waveguide 6. In order to ensure sufficient optical interference, the splitting ratio of the Y-shaped waveguide 6 should be as high as 1:1.
The invention provides an integrated chaotic signal generator based on a micro-ring and Y-shaped waveguide structure, which adopts two independent DFB chips to generate chaotic laser, utilizes a mutually coupled double-micro-ring waveguide to combine with the Y-shaped waveguide to carry out interference treatment on the chaotic light, effectively reduces the volume of a device and improves the dynamic characteristics of chaotic signals at the same time, and the integrated chaotic signal generator has the advantages of simple process and low cost, and is suitable for the fields of chaotic optical fiber sensing, chaotic secret communication and the like.
