Abstract

A wavelength dependent all-optical switching induced by side-mode injection locking behavior is experimentally demonstrated in single-mode Fabry-Pérot laser diode (SMFP-LD). The injection locking phenomenon is also observed while the peak wavelength at the injection beam is slightly shorter than that of the adjacent lasing mode, i.e. negative wavelength detuning, in which the obtained spectrum width is obviously extended compared to the case of positive wavelength detuning. As the wavelength detuning varies from ~0.35 nm to ~-0.2 nm with 3.5 dBm injection power, the on/off ratio of optical switching at dominated mode is remarkably decayed from ~50 dB to ~20 dB.
