Abstract:
A 9-channel wavelength tunable single-mode laser array based on slots is presented. The fabricated laser array demonstrated a threshold current in a range of 19~21 mA with the SOA unbiased at 20?C under continuous wave condition. Stable single mode performances have been observed with side-mode suppression-ratio (SMSR) >50 dB. The output power higher than 37 mW was obtained at the SOA injected current of 70 mA for all the 9 channels within the laser array. A wavelength quasicontinuous tuning range of about 27 nm has been achieved for the laser array with the temperature variations from 10?C to 45?C. This array platform is of a single growth and monolithically integrable. It can be easily fabricated by standard photolithography. In addition, it potentially removes the yield problem due to the uncertainty of the facet cleaving.
