Electro-optic Modulator

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is an improved electro-optic modulator that modulates light at a specified wavelength. It uses at least two doped semiconductor sections placed inside an optical resonator such that each section is located at an intensity minimum of the standing optical wave within the resonator. This arrangement enables high modulation efficiency with minimal optical loss, as the doped sections do not significantly interact with the light wave's areas of maximum intensity.

Patent Abstract

The invention relates to an electro-optic modulator (10) for modulating optical radiation of a prespecified wavelength, wherein the electro-optic modulator (10) has at least one optical resonator (20), in which for the prespecified wavelength a standing optical wave can form. According to the invention, provision is made for at least two doped semiconductor sections (33, 34) to be arranged in the resonator such that - when viewed in the longitudinal direction of the resonator - they are spaced apart from one another, and for the at least two doped semiconductor sections to be located in each case locally in an intensity minimum of the standing optical wave.
