Abstract
Bidirectional four-wave mixing (FWM) is investigated in a bulk
semiconductor optial amplifier (SOA) for dispersion compensation
and for the clear/drop functionality in optical time division
multiplexed OTDM) systems. Good performance for bidirectional
midspan spectral inversion (MSSI) is theoretically predicted for
bit rates of 10, 20 and 40 Gb/s and is shown to be in agreement
with measurements performed at 10 and 20 Gb/s. Measurements of the
clear/drop functionality using the bidirectional technique show
excellent performance for a 4 x 10 Gb/s signal and is again in
good agreement with simulations. The clear/drop functionality is
also simulated for 4 x 20 Gb/s and 4 x 40 Gb/s signals.
