Paper Abstract

The progress in selected areas of coherent lightwave systems technology at Bellcore over the past year is reviewed. Studies of the demodulator portion of a polarization diversity receiver show that a polarization sensitivity of less than 0. 5 dB can be achieved and that squaring circuits with wide dynamic range and very high sensitivity can be realized. We also report the results of frequency stability measurements made on packaged DFB laser transmitters over an extended time period. Four-wave-mixing (FWM) experiments show that high power in the range of 5 to 10 mW launched into dispersion shifted fiber can cause FWM crosstalk. Reports of FWM in a semiconductor optical amplifier are also reported. 1. )
