Abstract

Comparison of the frequency responses of two high-speed optical fiber processing elements is reported. The two filters we considered are a two-loops optical infinite impulse response (IIR) filter and a three-loops optical IIR filter. The theoretical models of these two kinds of optical IIR band pass filters are built up. Some suitable coupling coefficients are searched for simulating the narrow band- pass filters. The frequency responses under different conditions are analyzed. The theoretical models can provide parameter evaluation for experimental design. A higher design flexibility can be given by the three-loops optical IIR filter. These filters can be implemented with PIC (photonic PIC) techniques and applied for optical data signal processing.
