ABSTRACT:
An optical modulator is provided with a stripe-shaped optical waveguide, which has an upper clad layer, a lower clad layer formed between the upper clad layer and a substrate, and an undoped core layer which is arranged between the upper clad layer and the lower clad layer and has a complex refractive index that changes corresponding to the intensity of an applied electric field, to a signal light propagating inside. On both sides of the stripe-shaped optical waveguide, conductor walls are configured by arranging a pair of parallel blocking flat boards with an insulating wall in between. Thus, the semiconductor optical modulator having a high optical modulation efficiency is provided.
