Abstract :
A novel tunable single mode light source has been developed in the InGaAsP/InP material system. The Y-coupled cavity (YCC) type integrated interferometric injection (I3) wavelength tunable laser operates in the 1300 nm wavelength region with a sidemode suppression of about 20 dB. By adjusting the currents through the four all active sections of this YCC-I3-laser, a total tuning range of more than 14 nm and continuous tuning of 1.15 nm was obtained from non-optimised first devices.
