Abstract

We present an improved design of a wavelength-tunable single-mode laser array based on a high order surface grating with nonuniformly spaced slots. The laser array consists of 12 slotted singlemode lasers. The fabricated device exhibits a quasi-continuous tuning range of more than 36 nm over the temperature range from 10°C - 45°C covering the full C-band. All lasers in the array have stable single-mode operation with side mode suppression ratio of 50 dB due to the modified slot design. A spectral linewidth of less than 500 kHz was obtained for all channels in the array.
