Abstract :
We propose a noise suppression method using a feed forward circuit for injection-seeded WDM-PON. The required injection power is reduced by 8 dB by employing the proposed method. We investigate the limiting factors by tracing the relative intensity noise in the injection-seeded WDM-PON. Interplay of two filtering effects determines the net suppression of noise.
