Abstract

In vertical-cavity laser-diode arrays the emission wavelength of individual devices varies across the array, mostly because of inhomogeneous growth conditions. Moreover, device heating by laser-diode current produces an undesired shift of the emission line. We present a three-terminal laser structure that uses current-induced extra heating of the top mirror mesa for efficient wavelength control. Unlike the devices described in Refs. 1 and 2, three electrodes are accessible from the top surface and the device is fully monolithic.
