W. Idler et al., 10 GB S WAVELENGTH CONVERSION WITH INTEGRATED MULTIQUANTUM-WELL-BASED3-PORT MACH-ZEHNDER INTERFEROMETER/, IEEE photonics technology letters, 8(9), 1996, pp. 1163-1165
All-optical wavelength conversion of 10 Gb/s data with simultaneous re
generation of the extinction ratio is achieved by means of a monolithi
c 3-port Mach-Zehnder interferometer, The reported devices are based o
n an all active multiquantum-well waveguide structure with optical amp
lifiers in the input/output gates, Wavelength conversion is realized b
y optical cross-phase modulation in a counter propagative operation mo
de without applying an optical filter, The 3-port Mach-Zehnder interfe
rometer can provide either inversion or noninversion of wavelength con
verted 10 Gb/s data.
