Abstract

A new optimization method for the design of integrated band-pass traveling-wave modulator based on aperiodic domain-inverted grating is demonstrated. The frequency response of 10GHz and 20GHz (0.5dB) centered at 200GHz are presented. The physical mechanism for this kind of modulator is ascribed to the constructive interference effect of the overall domains. The sequences and the length of the domains are optimized to realize the pre-designed wide, flat frequency response over the required frequency range by use of the simulated annealing (SA) method.
