摘要

Diode lasers with an In_0.948Al_0.052Sb gain region have been grown by molecular beam epitaxy onto nominally matched InGaSb substrates, and onto mismatched InSb substrates. The former had a stimulated emission wavelength of 3.9μm at 77K, with the threshold current density being 140 Acm~-2 and maximum operating temperature 165K. The latter had a stimulated emission wavelength of 3.6μm at 77K, with the threshold current density being 417Acm~-2 and maximum operating temperature 160K.
