Integrated optical device with at least one optical waveguide integrated on a semiconductor substrate

摘要

1. Integrated optical device with at least one optical waveguide integrated on a semiconductor substrate. …??2.1. Low-loss passive and electrically controllable optical waveguides on a common semiconductor substrate, and their connection are to be capable of production as simply as possible. …??2.2. Use is made for this purpose of a ribbed waveguide defined by a rib (R1, R2) and a waveguiding layer (wS) of the substrate (S) and in whose region a pn or pin junction is provided in which the transition (Ü1, Ü2) from p-doped to n-doped or undoped material is arranged at a distance (D) from the waveguiding layer (wS), and the p-doped material is arranged on the side of said transition (Ü1, Ü2) averted from said layer (wS). …??2.3. Production of integrated optical switches, tunable integrated optical filters. …IMAGE…
