O. Leclerc et al., 40Gbit/s polarisation-insensitive and wavelength-independent InP Mach-Zehnder modulator for all-optical regeneration, ELECTR LETT, 35(9), 1999, pp. 730-731
A polarisation-independents, push-pull InP Mach-Zehnder modulator for 40Gbi
t/s all-optical regeneration has been implemented in a loop transmission sc
heme. Error-free regenerated transmission over >20000km was obtained. Wavel
ength independence and immunity to crosstalk were also measured, showing-th
e potential for WDM transmission applications.
