Id. Phillips et al., 40Gbit/s all-optical data regeneration and demultiplexing with long pattern lengths using a semiconductor nonlinear interferometer, ELECTR LETT, 34(24), 1998, pp. 2340-2342
40 Gbit/s, 2(31)-1 all-optical data regeneration and 40-10 Gbit/s regenerat
ive demultiplexing is demonstrated using a semiconductor nonlinear interfer
ometer incorporating an optimised optical amplifier. Error-free operation i
s achieved without simultaneous wavelength conversion. Such a device shows
great potential for use as a high-speed (greater than or equal to 40 Gbit/s
) all-optical 3R regenerator.
