Wavelength Conversion of 10-Gb/s RZ-OOK Using Filtered XPM in a Passive GaAs–AlGaAs Waveguide

Wavelength conversion of a 10-Gb/s return-to-zero on-off-keyed (RZ-OOK) signal has been achieved using transient cross-phase modulation in a passive GaAs-AlGaAs bulk-waveguide, followed by a detuned filter. The converted RZ-OOK signal showed a power penalty of <1 dB at a bit-error-rate of 10
^-9
relative to the baseline RZ-OOK signal.
