ABSTRACT Numerical investigation was done for the response of two semiconductor optical amplifiers (SOA) to direct modulation using three of the most commonly employed intensity modulation formats: non‐return‐to‐zero (NRZ), duobinary (DB) and quaternary pulse amplitude modulation (PAM‐4).

We demonstrate the feasibility of using a single microring resonator (MRR) as optical notch filter for enabling the direct modulation of a reflective semiconductor optical amplifier (RSOA) at more than tripled data rate than possible with the RSOA alone.

A Problem Analysis of RSOA-Based Optical Access
Using WDM multiplexing is one of the ways to increase PON bandwidth. But as WDM-PON is still expensive and difficult administered, the idea of using a Reflective Semiconductor Optical Amplifier (RSOA) is proposed. It can be installed in WDM-PON ONU network devices.
