Abstract

Official abstract text for this publication.

A semiconductor electro-optical phase shifter may include an optical action zone configured to be inserted in an optical waveguide, and a bipolar transistor structure configured so that, in operation, collector current of the bipolar transistor structure crosses the optical action zone perpendicular to the axis of the optical waveguide.

First claim

Opening claim text (preview).

That which is claimed is: 1. A method for controlling a phase shifter comprising an optical action zone coupled to an optical waveguide and a bipolar transistor configured so that collector current crosses the optical action zone transverse to an axis of the optical waveguide, the method comprising: applying a non-zero base-emitter bias current to the bipolar transistor; and modulating a collector voltage of the bipolar transistor. 2. The method according t…
