Guziy, O. (author), Grzanka, S. (author), Leszczynski, M. (author), Perlin, P. (author), Schemmann, M. (author), Salemink, H.W.M. (author) 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...
