 10GHz Tunable Picosecond Laser <MLLD-100> 
  - Wavelength Tunable, Hybrid Mode-Locked Laser Diode -

  The MLLD-100 is a tunable picosecond pulsed laser source based on a hybridly mode-locked semiconductor laser diode technology. The laser delivers a short pulse width of 2 ps with wavelength that covers the entire C-band window from 1530 to 1565 nm. The repetition pulse base rate is tuned via cavity length tuning around 10 GHz, making it a suitable pulse source for high-speed optical communication applications.
  The MLLD-100 operates in fundamental longitudinal mode (single pulse in a cavity round trip) yielding excellent stability with no pulse-to-pulse amplitude fluctuation, unlike other harmonically mode-locked fiber lasers which has multiple pulses in a cavity round trip, causing instability and required precise and complex phase-locking control for stabilisation. The pulse repetition rate of the MLLD-100 can be adjusted from 8.5GHz to 11.5GHz to match the required transmission bit-rate. Repetition rate locking to an external RF is possible for ultra stable operation.
