A novel all-optical wavelength converter based on the transverse-magnetic (TM)-mode
absorption modulation of a Fabry-Perot laser diode (FP-LD) is proposed and demonstrated.
An FP-LD shows absorption nulls for TM mode probe beam, which are red-shifted by an
additional optical pump injection. Using this, the transmission of the continuous-wave probe
beam can be optically controlled and wavelength conversion is, thus, achieved. The
proposed scheme is simple and cost-effective, and can be used for very wide-range …

An all-optical multi-wavelength converter using absorption modulation of an injection-locked
Fabry-Perot laser diode (FP-LD) is demonstrated at 2.5 Gb/s. The multi-wavelength
converter can simultaneously provide 1 to 4 channel outputs and support both inverted and
non-inverted conversion. By optimizing the wavelength of pump signal and polarization
states of pump, probes, and the FP-LD, all converted outputs show high extinction ratio and
negligible crosstalk power penalty. The results guarantee to increase the number of output …
