“…This signal is not regenerated, and the bandwidth-narrowing effect on the signal due to cascading AWGM filters [33], [34] may be an issue. It is worth noting that in [33], 10 cascaded narrow-band AWGM's (with the same 3-dB bandwidth and channel spacing as the AWGM used in our experiment in Fig.…”

We propose novel circuits for tunable all-optical wavelength converters with reconfigurable functionality. Circuits for wavelength converters based on cross-gain modulation (XGM) and cross-phase modulation (XPM) in semiconductor optical amplifiers (SOA's) are considered, for both copropagating and counterpropagating pump and probe signals. The circuits use arrayed-waveguide grating multiplexers (AWGM's) to filter and route signals in and out of the SOA's. The AWGM's minimize the component count in the circuits and may lead to future integration of wavelength converters. We experimentally demonstrate a XGM wavelength converter with copropagating pump and probe signals and report its bit-error-rate (BER) performance at 2.5 Gb/s.

“…A power penalty of approximately 3 dB at 10 Gb/s was measured. Forty broader-band AWGM's (3-dB bandwidth of approximately 1 nm) in cascade have been shown to give penalty-free performance at 10 Gb/s [34].…”
