研究目的
To accomplish the broadly wavelength tunability and single-longitudinal-mode (SLM) operation of erbium-doped fiber (EDF) based laser.
研究成果
The proposed EDF multiple-ring laser achieves SLM operation over a tuning range of 1520.0 to 1590.0 nm with output powers from ?7.3 to 5.1 dBm and OSNRs between 31.5 and 36.7 dB/0.06 nm. The laser demonstrates stable output with power and wavelength variations less than 0.7 dB and 0.04 nm over 60 minutes. The Lorentzian linewidth ranges from 14.9 to 20.4 kHz across the tuning range.
研究不足
The study does not explicitly mention limitations, but potential areas for optimization could include further reducing the Lorentzian linewidth and enhancing the output power stability across the entire tuning range.
