In this demonstration, we propose and experimentally investigate a widely C+L band wavelength-tunable fiber ring laser in continuous-wave (CW) tuning based on a hybrid semiconductor optical amplifier (SOA) and erbium-doped fiber amplifier (EDFA) in a serial scheme. When a hybrid first-stage SOA and second-stage EDFA is used inside ring cavity, the effectively amplification range can be extended from...
In this demonstration, we propose and experimentally investigate a broad and stable wavelength-tuning fiber laser employing a C-band erbium-doped fiber amplifier (EDFA) and coupled-ring cavity scheme. Based on the proposed laser scheme, the wavelength-tuning range can be tuned in S- to C-bands (from 1510.0 to 1562.0nm) due to the properly control of cavity loss. In addition, the performances of side-mode...
We propose and demonstrate an optical-burst-and-transient-equalizer (OBTE) on silicon-on-insulator (SOI) to provide a compact and low-cost solution to compensate gain- transient, gain-spectrum-tilt and to equalize the upstream packets amplitude in EDFA-amplified WDM-PON.
