M. Schilling et al., WAVELENGTH CONVERTER BASED ON INTEGRATED ALL-ACTIVE 3-PORT MACH-ZEHNDER INTERFEROMETER, Electronics Letters, 30(25), 1994, pp. 2128-2130
The realisation and first static results of a novel monolithic Mach-Ze
hnder interferometer (MZI) wavelength converter configuration in InGaA
sP/InP MQW technology is reported. The compact all-active three-port M
ZI device allows for effective improvement of the on/off ratio up to 1
8dB (from 6 to 26dB) due to direct optical access to one of the interf
erometer arms by an extra input branch. This device is very attractive
for high-capacity optical networks.
