Abstract
Tunable external-cavity lasers with low power variation over a broad tuning range are demonstrated using asymmetric multiple quantum-wells with a wide and flat gain. For a 2.8-μm-wide ridge waveguide laser of cavity length 380 μm, when used in a grating external cavity and with an antireflection coating on one facet of laser diode chip, the power variation of less than - 1 dB is obtained over a range of 80 nm. This extremely low power variation is a direct result of the spectrally flat gain. © 2005 IEEE.
