Continuous-wave operation of ZnSe-based laser diodeshomoepitaxially grown on semi-insulating ZnSe substrates

Abstract

Room temperature continuous-wave (CW) operation of a ZnSe-based blue-green laser diode, homo-epitaxially grown on semi-insulating ZnSe substrates, has been achieved. The threshold current and operation voltage under a CW electrical bias were 84 mA and 15 V, respectively. Under a pulsed electrical bias, lasing was achieved at up to 348 K. The characteristic temperature (T0) was 140 K between 253 and 318 K.
