Abstract
An electro absorption modulating apparatus is provided. A plurality of electro absorption modulators are disposed on a light transmission path. A controller controls a selection driving circuit to select one of the plurality of electro absorption modulators to perform light modulation on a light beam transmitted by the light transmission path, so as to generate a light modulation signal.
Claims10
An electro absorption modulating apparatus, comprising:
- an optical waveguide substrate, comprising a light channel, wherein the light channel provides at least one light transmission path to transmit at least one light beam;
- a plurality of electro absorption modulators, disposed on the at least one light transmission path, and optically coupled with the optical waveguide substrate, wherein each of the light transmission paths is configured with at least two electro absorption modulators;
- a selection driving circuit, directly coupled to the electro absorption modulators;
- and
- a controller, coupled to the selection driving circuit, and controlling the selection driving circuit to select and drive one of the plurality of electro absorption modulators corresponding to each of the light transmission paths to perform light modulation, so as to generate a corresponding light modulation signal.
