A Multiwavelength Low-Power Wavelength-Locked Slotted Fabry–PÉrot Laser Source for WDM Applications

摘要

Wavelength-locking of a multiwavelength stabilized slotted Fabry-Peacuterot (SFP) laser to a single-mode laser source is experimentally demonstrated. The SFP resonates at channels spaced by ~8 nm between 1510 and 1565 nm over a wide range of temperatures and drive currents. Under low-power (<-20 dBm) external optical injection, wavelength-locking with a sidemode suppression ratio (SMSR) >25 dB is achieved. A locking width of >25 GHz and SMSR >30 dB can be achieved for each locked wavelength channel at injection power >-16 dBm
