Abstract :
A digitally tunable laser that is based on a 12×12 waveguide grating router integrated with semiconductor optical amplifiers is demonstrated. The device emits on 12 wavelengths spaced exactly by 3.2 nm. ASE and sidemodes are suppressed by more than 40 dB. This laser is suitable for simultaneous multifrequency operation
