We present calculations which show that compressive or tensile strain introduced into the well material of InGaAsSb/AlGaSb quantum well lasers reduces the threshold current density compared with double heterostructure and lattice-matched lasers. The operating wavelength can be close to 2.55 mum, the region of lowest attenuation in fluoride glass fibres.
