Abstract:

Integrated Guided-Wave Optics has many advantages for the analog processing of optical wavefronts. These include small-size, high-speed, simplicity, reliability and reproducibility. The fabrication technique is similar to that of integrated circuits. The thrust of this program was to develop an integrated guide-wave optic system in GaAs and GaAlAs for use at GaAs laser wavelength, to remove aberrations from a laser beam and to steer the beam. The system would in addition have the capability to appropriately phase the outputs from a multiplicity of power amplifiers or injection locked lasers. It was also the intent of the program to design and build the optical circuits so they are compatible with on-chip electronic circuits in order to minimize the required number of off-chip leads
