Abstract

We present a novel parallel-ring-resonator tunable laser monolithically integrated with an InGaAlAs electroabsorption modulator. The fabricated tunable laser exhibits stable wavelength tuning with a step of 200 GHz over a wide tuning range of 35 nm, achieved with a single electrode control. The variation in the laser output power with wavelength tuning is less than 1 dB even at an injected tuning current of 20 mA. Clear eye openings at 25 Gbit/s with a dynamic extinction ratio of more than 10 dB are demonstrated over a wavelength range of 25.7 nm with a constant voltage swing of 2 V at 45°C. Error-free operation is confirmed under the same operating conditions.
