Abstract
Self-organised InAs quantum dots inserted in an (In, Ga)As matrix latt ice matched to an InP substrate are used as an active region in an inj ection laser. Low threshold (11.4A/cm(2)) lasing at 1.894 mu m (77K) v ia the states of the quantum dots is obtained. A material gain of the order of 10(4)cm(-1) is estimated.
