摘要	Disclosed are an apparatus and method for converting the wavelength of an optical signal using a multi-mode Fabry-Perot laser diode. The apparatus controls polarization of an external pump optical signal to output a TE polarized pump optical signal, and controls polarization of a probe optical signal to output a TM polarized probe optical signal. The apparatus couples the TM polarized probe optical signal and TE polarized pump optical signal irrespective of the polarization of the optical signals. The apparatus finely controls the polarization of the pump optical signal and the polarization of the probe optical signal such that they conform to TE and TM modes of the Fabry-Perot laser diode, respectively. The Fabry-Perot laser diode 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 the minimum intensity), to thereby convert the wavelength of the TE polarized pump optical signal to the wavelength of the TM polarized probe optical signal. Accordingly, a wide wavelength conversion band is provided, and inverting and non-inverting wavelength conversions are easily carried out.
