Abstract

We demonstrate completely integrated tunable coupled cavity InGaN/GaN lasers with emission wavelength centered on 409 nm. Threshold currents are 650 mA per cavity for 8.7 um wide laser ridges. Experimental tuning map is explained with estimation of refractive index change due to free carrier injection and the Vernier effect. Multimode laser emission with the average full width half maximum of 0.3 nm, electronic tuning range of 1.6 nm and thermal tuning range of 2.4nm is observed.
