Semiconductor external optical modulator |
摘要 |
A semiconductor external modulator is disclosed in which the mode of polarization of incident light, the crystal plane of the substrate (the direction of application of an electrical field), the energy gap of the optical waveguide layer, and the direction of travel of light are determined so that, of variations in the real and imaginary parts of the refractive index of the optical waveguide layer which are caused by the application of the electric field to the semiconductor external optical modulator, the variation in the real part of the refractive index may be reduced to substantially zero.
