Chamings, J, Adams, AR, Sweeney, SJ, Kunert, B, Volz, K and Stolz, W (2008) Temperature dependence and physical properties of Ga(NAsP)/GaP semiconductor lasers APPLIED PHYSICS LETTERS, 93 (10), ARTN 1.
We report on the properties of GaNAsP/GaP lasers which offer a potential route to producing lasers monolithically on silicon. Lasing has been observed over a wide temperature range with pulsed threshold current density of 2.5 kA/cm2 at 80 K (lambda=890nm). Temperature dependence measurements show that the radiative component of the threshold is relatively temperature stable while the overall threshold current is temperature sensitive. A sublinear variation of spontaneous emission versus current coupled with a decrease in external quantum efficiency with increasing temperature and an increase in threshold current with hydrostatic pressure implies that a carrier leakage path is the dominant carrier recombination mechanism.
