Microwave performance prediction of a III-V semiconductor electrooptic waveguide modulator.

The use of microwave modulations of optical waves allows one to obtain devices with very large bandwidths. Designers must solve two problems, one more specifically relevant to the optical field, the other in the microwave frequency range. The purpose of this paper is to focus the attention of optical device designers on microwave problems that occur when such modulators are made. To do so, we give some quantitative results relative to the microwave characteristics of such devices, when the hybrid nature of the microwave mode is taken into account.
