Abstract

We simulate the injection-locking performance of a 1% antireflection coated Fabry–Perot laser amplifier (AR-FPLA) and demonstrate the 2.5-Gbit/s DWDM-PON application with the directly modulated AR-FPLA based ONU transmitter under side-mode injection-locking condition. The effect of the AR-FPLA front-facet reflectivity on the injection locking range detuning and the $Q$-factor are interpreted from theoretical simulations and are experimentally characterized. A 25-channel locking capacity is reported for such a side-mode injection-locked AR-FPLA with corresponding wavelength locking range of 30 nm, the minimal requested power of ${-}7$ dBm and gain extinction ratio of $<7$ dB by reducing its front-facet reflectivity to 1%. At bit rate of 2.5 Gbit/s, the BER of $10^{-12}$ is achievable for the nearest 17 channels of AR-FPLA at receiving power of $- 21$ dBm, and all of the 25 injection-locked channels with SMSR of $> 35$ dB can guarantee the BER of $< 10^{-9}$ with their worst receiving sensitivity degrading to $- 19$ dBm.
