Faculty Electrical Engineering, Mathematics and Computer Science Department Quantum Nanoscience Date 2012-08-01 Abstract We demonstrate an integrated tunable coupled-cavity InGaN/GaN laser with the emission wavelength centered on 409 nm. The electronic tuning range was 1.6 nm and threshold currents were 650 mA per cavity for 8.7-?m-wide laser ridges. Multimode laser emission with an average full width at half maximum of 0.3 nm was observed. We estimate the refractive index change due to free-carrier injection and optical gain to explain the experimental tuning range.
