Multiplexing and Filtering of Optical Signals.
Abstract
The objective of this contract is to develop an optical multiplexing device to combine onto one channel the information carried on several separate fiber optic channels and, subsequently, to perform the demultiplexing operation after transmission over distances of the order of a km. The main research effort is the development of the optical multiplexing/demultiplexing device. This device must be compatible with multimode fibers of relatively large numerical aperture, exhibit total throughout losses less than 15 dB, total signal to crosstalk ratio of more than 20 dB, and a bandwidth capability of 1.3 MHz. This report covers the work performed during the first six months of this contract, from May through October 1976. During this period the required work on the multiplexer device was nearly completed, and at the point all but one of the criteria outlined above have been met. Specifically, several devices have throughput losses of 10-15 dB are capable of working with large NA fibers, and have bandwidths of 100 MHz have been constructed. At this time only one requirement has not been fully met; that is, 10 dB signal to crosstalk has been obtained as opposed to 20 dB. However, several new devices, which are near completion, have been designed to improve the results in this area. (Author)
