Abstract
As part of the activities of the ARPA-funded, Ultra-Fast Optical Communication Consortium, hardware is being developed which is designed to provide an interface between a parallel array of 1 Gb/s electronic data sources and a 100 Gb/s, single-wavelength fiber optic channel. The input device is an integrated-optic tapped delay line (TDL) whose taps are set by the parallel electrical data streams which are then strobed by a 2 psec pulse to create an n-but optical word with an internal data rate of 100 Gb/s. A prototype device which uses arrays of fixed TIPE gratings for beam splitting and combining and which uses an array of electro-optic gratings as switched is currently being fabricated in a planar LiNbO3 waveguide. Preliminary results and alternative TDL designs will be discussed. The output device, which employs waveguide second harmonic generation in a specially-designed GaAlAs waveguide, converts the temporal optical word into a spatial array of optical signals which can be detected in parallel. Experimental results will be presented which demonstrate that the serial-to-parallel converter can operate at rates exceeding 100 Gb/s, and can be expected to result in bit error rates of better than 10-9 in a high-speed data link. The use of the integrated optic devices in CDMA as well as TDMA systems will be discussed.
