Abstract :
A novel scheme for a digitally tunable laser requiring only P+Q+1 optical amplifiers for a device with in total P × Q wavelength channels is presented A 32-channel InP/InGaAsP based device is fabricated. An optimised active layer and low on-chip losses result in a high optical output power.
