ABSTRACT:
A semiconductor optical modulator which, with a relatively simple configuration, eliminates phase modulation of output light from the semiconductor optical modulator by applying a voltage to a light absorption layer on the modulator. A nonlinear optical material layer changing refractive index is located in the direction of light propagation and cancels, in the output light, the phase modulation that is generated due to light intensity variations in the light absorption layer.
