The objectives of this contract are to study and analyze the propagation, attenuation, and modulation of coherent optical waves in thin film waveguides, in particular epitaxial semiconductor structures at a wavelength of 8500A, to determine the parameters controlling the solution regrowth epitaxy of the Ga1-xAlxAs system, to study the influence of the index discontinuity and semiconductor carrier concentration on optical properties, and to develop the elementary optical device elements. The present program may be viewed as consisting of the following elements 1 establishment of epilayer material and structure requirements from the device point of view, 2 development of materials growth techniques, 3 materials evaluation, and 4 device analysis and fabrication techniques.
