We present our first experimental results of a monolithically integrated continuously tunable laser source for optical coherence tomography in the 1.6 to 1.8μm wavelength region. The InP-based active-passive integrated ring laser system contains three 8mm long InAs/InP(100) quantum-dot amplifiers and two electro-optically tunable filters. Initial results show a tuning range of at least 20nm, 25dB side mode suppression and a linewidth better than 0.05nm. We present details on the calibration and performance of the tuning filters in the laser.
