Abstract
This invention discloses a selectably directable optical beam generating device including at least one light source, and at least one substrate, each having formed thereon a multiplicity of waveguides, each waveguide receiving light from the at least one light source and emitting light, the totality of light emitted by the multiplicity of waveguides producing at least one selectably directable output beam.
Claims18
An optical device comprising:
- a multiplicity of electrically controlled waveguides formed on at least one gallium arsenide substrate, each of said at least one substrate comprising layers of materials arranged to confine an electrical field in a relatively small thickness and wherein the said layers include:
- an N-doped gallium arsenide substrate;
- an N-doped aluminum gallium arsenide layer formed over said substrate;
- an N-doped gallium arsenide layer formed over the N-doped aluminum gallium arsenide layer;
- a P-doped gallium arsenide layer formed over the N-doped gallium arsenide layer;
- a P-doped aluminum gallium arsenide layer formed over the P-doped gallium arsenide layer;
- and
- a P-doped gallium arsenide layer formed over the P-doped aluminum gallium arsenide layer;
- and
- a polarization rotator for rotating the polarization of light passing through said multiplicity of electrically controlled waveguides.
