Paper Abstract

Signal processing applications for integrated optical devices which have been proposed and currently under active study include rf spectrum analysis, analog to digital conversion, heterodyne optical reception, pulse compression, digital logic, and correlation filtering. For these applications, integrated optics offers the potential of improved performance due to the lower power consumption and higher speed which results from miniaturization. Once fabrication problems have been solved, several fundamental effects must be considered as limits on performance. For example, acoustic velocity and attenuation taken together determine the achievable time-bandwidth product for integrated optic acoustic devices just as they do for their larger bulk equivalents. Power requirements of integrated optical devices can present problems of optical or electrical damage caused by the increased energy density resulting from miniaturization. In devices such as the spectrum analyzer in which signals are represented by deflected light beams in the plane of the waveguide, the quality and design of the various components such as lenses and couplers and the guides themselves, set performance limits on application of integrated optic processors.
