Abstract
We demonstrate an 8-frequency digitally tunable laser based on a waveguide grating router with an electroabsorption modulated output. The laser wavelengths range from 1.567 to 1.580 /spl mu/m with channel spacings of 200 GHz (1.6 nm). The modulator extinction is -10 dB/VN with a -5-V bias. A unique output coupler design delivers an ASE noise suppression of -55 dB//spl Aring/.Keywords
