Abstract

We report on a quantum dot laser having an emission spectrum as broad as 74 . 9 nm at 25°C in the 1.2–1.28 wavelength interval with a total pulsed output power of 750 mW in single lateral mode regime and the average spectral power density of > 10 mW nm . A significant overlap and approximate equalization of the ground-state and the excited-state emission bands in the laser’s spectrum is achieved by means of intentional inhomogeneous broadening of the quantum dot energy levels.
