Design of a Fiber Optical Integrator for Optical Computing

摘要

We present a novel optical integrator with a semiconductor optical amplifier (SOA) and an infinite impulse response fiber optical loop filter in this paper. Adjusting the filter parameters, we can achieve an integrator that can execute integration in a short pulse period. Because the infinite impulse response filter includes a 2X2 electro-optical (E/O) switch, the pulse shape after the integration can be varied according to an external driving voltage. According to the calculation result, the gain coefficient of SOA can provide a design flexibility for approaching a real integration.
