Abstract

We present measurements of wavelength switching under current modulation in a dual-contact two-color diode laser. The Fabry-Pérot laser diode considered is designed to support only two primary modes with a spacing of 480 GHz. A heterodyne measurement of the switching dynamics with modulation of the drive current of the long contact shows switching of the intensity in times of 2 ns with 30-dB contrast ratio.
