Abstract:
1. An optical wavelength converter using injection locking of a Fabry-Perot laser diode, which converts the wavelength of an optical signal received from the outside, comprising: a first polarization controller that controls polarization of a pump optical signal to output a TE polarized pump optical signal; a second polarization controller that controls polarization of a probe optical signal to output a TM polarized probe optical signal; a photo-coupler that couples the TM polarized probe optical signal and TE polarized pump optical signal; a Fabry-Perot laser diode that injection-locks the TE polarized pump optical signal of the coupled signal to change the position of a TM mode absorption null (a point at which an output optical signal has a minimum intensity), to thereby convert the wavelength of the TE polarized pump optical signal to the wavelength of the TM polarized probe optical signal; and a circulator that outputs the probe optical signal to the outside.
