Paper Abstract

A fiber-optic/integrated optic optoelectronic neural computer approach to the design of an 'intelligent' aerospace structure is described, and the methodology of the approach is defined. A source consisting of a strained-layer QW laser emitting 100 micro-W at 978 nm and an Er-doped single-mode polarization preserving fiber laser with a gain of 3.9 dB/mW is assumed. The SNR for the aerospace plane is calculated with 49 sensing arms. A 441-path splitter is required; this is designed using an eight-stage multipath coupler based on a 3X3 polarizer/splitter as the basic repeating element. A surface-mounted implementation is suggested, which includes a 448-path switch, an integrated-optic coupler, a detector, an ADC, and a processor.
