Abstract :
We describe a 12-element distributed feedback laser array, with 10-μm pitch, covering a 36-nm tuning range, and having an integrated heater on each element. The novel heater design heats just the active laser yet requires only one additional contact for the entire array. Each individual laser element can be temperature tuned more than 3.2 nm in under 100 μs using its heater.
