Abstract: Embodiments of the present disclosure provide a self-injection laser, a WDM-PON system and an optical line terminal. The self-injection laser includes a gain medium, an array waveguide grating AWG, a periodic filter and a reflection module. The AWG is configured to multiplex an optical signal received from the gain medium via the branch port, and output the multiplexed optical signal via the common port. The periodic filter is configured to filter the optical signal output by the AWG, where at least a part of the filtered optical signal is reflected by the reflection module, and the reflected signal is returned back and injected to the gain medium.
