摘要:
An optical source for wavelength division multiplexed optical network according to the present invention comprises a broadband light source (BLS); an arrayed waveguide grating (AWG) for spectrum-dividing incoherent light outputted from the BLS; a circulator being connected between the BLS and the AWG; and a plurality of un-polarized light sources (UPLS) being respectively connected to the AWG, wherein the incoherent light which is spectrum-divided by the AWG is injected into the plurality of UPLS and thus the plurality of UPLS is wavelength-locked thereto. In case of using an optical source for wavelength division multiplexed optical network and a wavelength division multiplexed-passive optical network having the same according to the present invention. It is especially possible to lower dramatically the power of incoherent light being injected into a wavelength-locked Fabry-Perot laser diode, while to enable a high transmission speed of 1.25 Gb/s or more, and possible to further lower noise intensity of a light source at given power of the incoherent light.
