Abstract :
We demonstrate a 16-wavelength gain-coupled DFB laser array with a post-fabrication fine tunability. The array consists of 16 InGaAsP/InP strained layer MQW ridge waveguide lasers with ridge widths from 1.6 to 5.2 μm. Our experimental results have shown that all lasers had single-mode lasing at expected Bragg wavelengths in cw operation; 16 lasing wavelengths around 1.55 μm with ∼l nm spacing were obtained. A thermal fine-tuning for the individual lasers was obtained with a Ti thin-film resistor.
