C. Joergensen et al., WAVELENGTH CONVERSION BY OPTIMIZED MONOLITHIC INTEGRATED MACH-ZEHNDERINTERFEROMETER, IEEE photonics technology letters, 8(4), 1996, pp. 521-523
Semiconductor optical amplifiers have been monolithic integrated in a
passive symmetric Mach-Zehnder interferometer to form a compact polari
zation insensitive all-optical wavelength converter operating at up to
10 Gb/s, A simple method for reducing the impact of input power varia
tions is proposed that increases the input power dynamic range from 4-
8 dB.
