F. Ratovelomanana et al., REGENERATION IMPROVEMENT IN ALL-OPTICAL WAVELENGTH CONVERTER, BASED ON A MACH-ZEHNDER INTERFEROMETER, BY MEANS OF PHASE-SHIFTER SECTION, Electronics Letters, 33(19), 1997, pp. 1629-1630
A passive phase-section is integrated in one arm of an interferometric
all-optical wavelength converter. The passive phase-section is demons
trated to increase the extinction ratio regeneration capabilities of t
he converter by 10dB and to improve the receiver sensitivity by 3.9dB,
for the converted signal at 2.5Gbit/s.
