The present invention relates to an optical modulation method and optical modulation system of a wavelength locked Fabry Perot-Laser Diode (FP-LD) by injecting a broadband light source (BLS) using mutual injection of FP-LDs. More specifically, the present invention relates to a novel modulation technology which embodies a wavelength locked FP-LD capable of being used as an economic light source in an optical network based on a wavelength-division multiplexing passive optical network (WDM-PON). According to the present invention, a light modulation system is suggested comprising: BLS being constructed by mutual injection between two FP-LDs and an optical fiber being used for light transmission; first AWG for filtering light from a plurality of oscillation modes of the BLS into n group; n FP-LDs outputting wavelength locked light which is divided through the first AWG; an encoder being provided at a transmitting end of a subscriber to which the output from the first AWG is transmitted; a circulator outputting light which is inputted through the first AWG; second AWG de-multiplexing WDM signals from the first AWG into n group; and a decoder being provided at a receiving end to which the output from the second AWG is transmitted. Therefore, the present invention makes it possible to provide a more economic light source for WDM-PON subscribers by embodying a wavelength locked FP-LD by injecting a low-cost BLS.
