Abstract

A detailed analysis of an integrated optical finite impulse response filter architecture is presented. The output signal attenuation caused by the light propagation loss in a LiNbO₃ waveguide, and the diffracted light pulse time dispersion due to the tilted position of device electrooptic gratings, are analyzed. In addition, problems that arise from the inaccurate filter coefficient implementation as well as performance evaluation and design limitations are discussed. Finally, a low pass filter is designed, and its characteristics are compared to the theory.
