Under injection-locking with downstream amplified spontaneous emission (ASE) carrier spectrally sliced by a 200-GHz arrayed waveguide grating and amplitude-squeezed by a gain-saturated semiconductor optical amplifier (SOA), the injection-level-dependent extinction ratio (ER) and bit-error-rate (BER) penalty of a weak-resonant-cavity Fabry-Perot laser diode (WRC-FPLD) upstream transmitter are investigated...
Criterion on extinction ratio and overshooting level of smaller than 3dB and -5dB, respectively, for The SOA amplitude squeezed ASE data-stream to injection-lock the weak-resonant-cavity laser diode transmitter approaching BER<;;10-9 at 2.5 Gbit/s is reported.
The BER and noise characteristics of 1.25Gbit/s directly modulated ASE injection-locked mode-number tunable weak-resonant-cavity laser diode transmitter for WDM-PON system with channel spacing of 200GHz are characterized.
We demonstrate dual low-facet-reflectivity FPLD amplitude squeezers to suppress extinction ratio of down-stream signal by 8.6 dB for injection-locking RSOA in DWDM-PON with error-free 1.25 Gbps up-stream transmission at receiving power of -25.5 dBm.
