We propose an alternative training regimen using gradient based regularization terms in the training objective that are found to impart some degree of fault tolerance and noise immunity in comparison to injection based training regimen. Each option effectively reduces feedback in the external cavity of diode laser systems and blocks reflections from free-space fiber coupling.

Training regimens based on intentional fault and noise injection during the training phase are only found marginally successful at imparting fault tolerance or noise immunity. Free-Space Optical Isolators incorporate a Faraday Rotator and are specifically designed and manufactured to provide superior performance with high isolation, transmission, and power densities. Considering diffractive optical networks trained for image classification tasks on standard datasets, we numerically study the performance degradation arising out of weight faults and injected noises and methods to ameliorate these effects. Being analog systems, these engines are also subject to performance degradation due to noises in the inputs and during optoelectronic conversion.

Although this process of weight transfer has many practical advantages, it is often accompanied by performance degrading faults in the fabricated hardware. Free Space Optical Communication (FSO) offers highly directional, high bandwidth communication channels between two devices. The training phase of such systems is usually performed in a computer and the learned weights are then transferred onto optical hardware ('ex-situ training'). Hardware that integrates with the system emulation test bench for design optimization. Field programmable gate array (FPGA) hardware for use in satellite cross link and laser terminal system segments. QinetiQ believes that Free Space Optical Communications (FSOC) a technology originating in the commercial sector, offers true innovation that will unlock. Optical downlinks in a fading channel with high-speed FECs and channel interleavers. Free-space diffractive optical networks are a class of trainable optical media that are currently being explored as a novel hardware platform for neural engines. Free space optical links for 2.5G, 10G, 40G.
