Abstract :
The tunable twin-guide (TTG) structure has been realised with the metal-clad ridge-waveguide (MCRW) distributed feedback (DFB) laser yielding continuous tuning up to 2 nm, output power above 10 mW and linewidth below 10 MHz. The relatively simple fabrication technology and high reliability make this device well suited as a tunable light source for advanced optical communication systems.
