Broad Bandwidth Optical Modulator and Switch.

摘要

The patent application describes a modulator and switch for optical energy which includes an optical waveguide defining a path for the propagation of optical energy, a source of microwave energy, and at least one strip transmission line disposed in co-directional proximity relative to the optical waveguide and connected to the source of microwave energy. The strip transmission line is designed to have dimensions and dielectric constants for producing a propagation velocity of the microwave energy substantially equal to the propagation velocity of the optical energy in the optical waveguide. A suitable microwave load is connected to the transmission line for completing an electrical circuit with the source of microwave energy.
