A SYSTEM AND METHOD FOR ENABLING AN OPTO-MECHANICS BASED HIGH DATA RATE TRANSMISSION AND RECEPTION

RELATED PATENT APPLICATION(S):

This application claims the priority to and benefit of Indian Provisional Patent Application No. 202141039834 filed on September 02, 2021; the disclosures of which are incorporated herein by reference.

FIELD OF THE INVENTION:

The present invention relates to hardware design in communication technology domain. Specifically, the invention relates to a system and method for enabling an opto-mechanics based high data rate transmission and reception. More specifically, the said method and system for enabling a dynamic optics based transmission and reception uses dynamic axial movements and angular movements of an optical unit.

BACKGROUND OF THE INVENTION:

When the system has ability to process significant load of data, the system needs to be provided with adequate data at a required rate. In traditional systems, number of instructions executed by the processor would be proportional to the rate at which data is received. In such cases, scheduling algorithms associated with operating systems would be able to enable effective resource utilization. When the system has capacity to execute instructions at an improved rate, and if the instructions to be executed are not fetched at the required rate, it would affect resource utilization cycle of the system.

Hence, there is a need for a communication system which is designed for high performance computing applications. For efficient enablement of the system, there is a need for utilizing multiple technologies along with packaging methodologies. Further, to supplement the systems which are designed for high performance computing applications, there is a need for developing a high data-rate communication mechanism both for inter- system communication and for intra- system communication with thermal stability.

In case of alignment of photo detectors, generally high data rate photo detectors have small aperture of the order of 30-60um and aligning a transmit beam into such small area accurately is a challenge. As retro -reflector are designed to work at low data rate. Hence, there is a need to address the above-mentioned challenge.

Also, there is requirement to eliminate need of a pilot beacon in an alignment test setup. Beacons co-mounted with transmitters are traditionally used as alignment guides where the received beacon data provides angular and spatial information about the position of transmitter. Such beacons require their own source, driver circuitry, receiver circuitry and integration with the transmitter and receiver. This imposes hardware complexity, need for feedback control and causes optical noise in the data channel.

Furthermore, there is also a need to achieve high data rate using a simple structure that eliminates repeated use of a pilot beacon, and optical fibers and achieve a high coupling efficiency, and cost.

FIGURE-2:

FIG 2 represents a block diagram of the enabling the dynamic optics based (optomechanics based) transmission and reception, according to one embodiment of the invention. In some example embodiments, the transmitter unit (101) may transmit a first optical signal (201a) proportional to a first electrical signal obtained by the transmitter (101). In some example embodiments, the transmitter unit (101) may be a FPGA, associated with a circuitry to generate a first optical signal (201a) proportional to the obtained first electrical signal.

In some example embodiments, the first optical signal (201a) is directed towards an optical unit (105). The optical unit (105) may comprise a prism based lens assembly. The prism based lens assembly may consists two edges of angle (a’) and (a”) respectively on a left plane (105a) and a right plane (105b). Further, a top plane of the prism based lens assembly does not allow the any optical signal to pass through and a bottom plane may be transparent and allows the first optical signal (201a) to pass through.

The first optical signal (201a) hits the left plane (105a) of the optical unit (105) and due to TIR the signal is reflected inside the optical unit (105). Thus, the second optical signal (201b) is formed.

The left plane (105a) and the right plane (105b) of the optical units (105) formed angle (a’) and (a”) respectively enable formation of the Total Internal Reflection (TIR). In some example embodiments, both of the angles (a’ and a”) may be forty-five degrees each.

Similarly, the first electrical signal and the second electrical signal may contain the same information.

FIGURES 3A-3F:

FIGs. 3A and 3B illustrate construction of the dynamic optics based (opto- mechanics based) transmission and reception system using an exemplary scenario, according to one embodiment of the invention. Construction of the optical unit (105) includes placement of the prism based lens assembly (301) on a first dynamic surface (303a) and a second dynamic surface (303b) (collectively be referred as dynamic surfaces (303)), such that the dynamic surfaces (303a and 303b) are moveable on a static surface (305). Dynamic adjustment of the prism lens assembly (301) is enabled by a horizontal setter (307a), a vertical setter (307b) and a pair of angular setters (309). The pair of angular setters (309) are represented as (309a) and (309b) respectively. In some example embodiments, the angular setters (309) enable transmission and reception of optical signals respectively. Each rotation of screw associated with the horizontal setter (307a) and the vertical setter (307b) moves the prism assembly (301) by 500 micrometer along X-axis and Y-axis respectively.

The dynamic optics based transmission and reception is enabled by an optomechanics coupling mechanism. Further, the opto-mechanics based coupling mechanism involves coupling the multiple channels of optical signals from a transmitter unit (101 of figure 1) to a receiver unit (103 of figure 1) by executing fine mechanical adjustments to the prism lens assembly (301) (also known as retroreflectors). The fine mechanical adjustments include moving the prism lens assembly (301) along X-plane, Y-plane and adjusting the angle of transmission and reception, associated with the multiple channels of optical signals.

In some example embodiments, fine mechanical adjustments in the X-plane is achieved by using the horizontal setter (307a) that is associated with first dynamic surface (303a) and fine mechanical adjustment in the Y-pane is achieved by the vertical setter (307b), that is associated with second dynamic surface (303b). The horizontal setter (307a) and the vertical setter (307b) comprise two screws (not shown) where one is firmly attached to static surface (305) and other is moveable on the dynamic surface (303). In some example embodiments, with respect to the horizontal setter (307a), clockwise movement of the moveable screw moves the static surface (305) towards left side, thereby making the lens assembly (301) move to left. In some other example embodiments, with respect to the horizontal setter (307a), anti-clockwise movement of the moveable screw moves the static surface (305) towards right side, thereby making the lens assembly (301) move to right. Further, movement of the lens assembly (301) is enabled by movement of the first dynamic surface (303a), that moves the lens assembly (301). In addition, the first dynamic surface (303a) may comprises a spring load structure on two opposites ends of the first dynamic surface (303a), along the X-axis such that the lens assembly (301) may firmly be placed at any required position based on application of compression and decompression force applied by the spring load structure along the X-axis. The spring load structure along the X-axis may be enabled by the movement of the horizontal setter (307a), associated with the first dynamic surface (303a). In some example embodiments, the spring load structure may cushion the left side movement and/or right-side movement of the lens assembly (301).

In some example embodiments, with respect to the vertical setter (307b), clockwise movement of the moveable screw moves the second dynamic surface (303b) first side-wards, thereby making the lens assembly (301) move towards one side. In some other example embodiments, with respect to the vertical setter (307b), anticlockwise movement of the moveable screw moves the second dynamic surface (303b) second side-wards, thereby making the lens assembly (301) move towards opposite side. Also, the first side-wards movement and the second side-wards movement are opposite in nature. In addition, the second dynamic surface (303b) may also comprises another spring load structure on two opposites ends of the second dynamic surface (303b), along the Y-axis such that the lens assembly (301) may firmly be placed at any required position based on application of compression and decompression force applied by the spring load structure along the Y-axis. The spring load structure along the Y-axis may be enabled by the movement of the vertical setter (307b), associated with the second dynamic surface (303b). In some example embodiments, the spring load structure may cushion the side-wards movement of the lens assembly (301).

In some example embodiments, to execute fine adjustment with respect to angular plane, height of the pair of angular setters (309), with respect to a surface of the transmitter unit (101) and the receiver unit (103). For example, to achieve a certain degree of ‘t’ at both transmitter and receiver side, length of the angular setters (309) is varied using a height adjustment mechanism. In some example embodiments, difference in the height of one of the angular setters (309a) of the pair of angular setters (309), with respect to the other angular setter (309b) of the pair of angular setters (309) cause a difference in planar height that enables change in angle ‘t’ . The opto-mechanics explained in the above description enables passive alignment. Working of opto-mechanics based coupling of multiple channels may be explained in the FIGs. 3C-3D.

FIG. 3C illustrates working of multi-channel coupling at transmitter unit (101) and reception unit (103) respectively, using an exemplary scenario, according to one embodiment of the invention. In some example embodiments, a high data rate bit pattern generator may be use to generate multiple multi-gigabit rate arbitrary serial bit pattern (i.e., a first set of electrical signals), the transmitter unit (101) may convert the serial bit pattern into multiple optical signals (in some cases referred as optical pulses) and sent towards the optical unit (105) for coupling. At the receiver unit (103), multiple optical signals are converted back to the serial bit pattern (i.e., a second set of electrical signals) and the received serial bit pattern may be subjected to evaluation of data integrity by a circuitry.

The circuitry may further evaluate the generated pattern and received pattern and provides a pass/ fail signal based on the integrity of data. In some example embodiments, the circuitry may comprise a processor and a memory. The processor can be any processor, such as 32-bit processors using a flat address space, such as a Hitachi SHI, an Intel 960, an Intel 80386, a Motorola 68020 (or any other processors carrying similar or bigger addressing space). Processors other than the above mentioned, processors that may be built in the future are also apt. The processor can include but is not limited to general processor, Application Specific Integrated Circuit (ASIC), Digital Signal Processing (DSP) chip, AT89S52 microcontroller firmware or a combination, Field Programmable Gate Arrays (FPGAs) thereof.

Processors which are suitable for carrying out a computer program may include, by example, both special and general-purpose microprocessors, or processors of any kind for digital computer. Generally, a processor obtains instructions and data through a read only memory card or a random-access memory (RAM) or both. The vital elements of a computer are its processor for carrying out instructions and multiple memory devices for hoarding data and instructions. Generally, a computer includes, or be operatively associated to transfer data to or receive data from, or both, multiple mass storage devices for hoarding data, e.g., magneto optical disks, magnetic, or optical disks. However, a computer requires no such devices. Moreover, a computer can be lodged into another device without much effort, e.g., a personal digital assistant (PDA), a mobile telephone, a GPS receiver, a mobile audio player, to name a few. Computer readable media which are suitable for hoarding computer programs and data consists of all forms of media, and memory devices, non-volatile memory, including semiconductor memory devices, e.g., EEPROM, EPROM, and magnetic disks, flash memory devices; e.g., removable disks or internal hard disks ; magneto optical disks, DVD-ROM disks and CD ROM . The memory can be of non-transitory form such as a RAM, ROM, flash memory, etc. The processor along with the memory can be supplemented by, or subsumed in, special purpose logic circuits.

In accordance with an example embodiment, the memory includes both static memory (e.g., ROM, CD-ROM, etc.) and dynamic memory (e.g., RAM, magnetic disk, writable optical disk, etc.) for hoarding the executable instructions which when executed perform evaluation of the data integrity.

Further, the transmitter unit (101) and receiver unit (103) may be placed on a socket in a single Printed Wire Board (PWB) for convenience of usage and testing. FIG. 3C further describes mechanism of divergence and convergence of optical signals (311) at transmitter unit (101) and receiver unit (103). At transmitter unit (101), the generated optical signals are divided into multiple channels using a divergence lens and at receiver unit (103), multiple channels of optical signals is obtained using a convergence lens. The multiple channels are coupled using opto-mechanical mechanism, which may be described in FIG. 3D. FIG. 3D illustrates working of multi-channel coupling at the prism lens assembly (301) using an exemplary scenario, according to one embodiment of the invention. As explained in FIG. 3A and 3B opto-mechanical coupling, comprise executing fine mechanical adjustments. The fine mechanical adjustments enable a firm set up of open loop passive aligner that enables transmission and reception of the optical signals in the multi-channel, at a very high data rate. FIG. 3D illustrates the firm set up of open loop passive aligner that enables transmission and reception of the optical signals in the multi-channel (31 la, 31 lb, and 311c), at a very high data rate through the lens assembly (105).

Normally, the lens assembly (105) (i.e. retro reflectors) are aligned using a pilot beacon that is different from the optical signals. The beacon provides the required information about the retro -reflector (i.e. the lens assembly (105)) positioning accuracy and allows the operator to adjust the retro-reflector prior to testing. In the present disclosure need of the pilot beacon is eliminated there by easing the complexity and cost of the setup. In some example embodiment, multiple channels might include at least 12 channels.

In some example embodiments, significant power saving may be achieved by eliminating quadrant detection system that is used configure the pilot beacon (i.e. LP LASER of wider FoV) by detecting a change that deviates from an ideal coupling of transmitter and receiver, in a closed loop system. The ideal coupling includes an alignment where ration of power received at the receiver and the power transmitted at the transmitter, that is associated with the optical signals is maximum.

Further, by eliminating the pilot beacon based alignment process of closed loop passive alignment is further enhanced by introducing direct optical signal based alignment using the lens assembly (105), where function of the pilot beacon may be executed by subjecting a buffer optical signal through the closed loop optomechanical system described above. In addition, it may also be observed that elimination of need of the pilot becomes removes need of associated constriction elements, thereby making the construction and coupling, between the transmitter and the receiver efficient and cost effective.
