Abstract :
Summary form only given. Recently we have proposed and demonstrated a novel tunnel-injection mid-IR laser based on type II broken-gap p-GaInAsSb/p-InAs heterostructure placed in the active layer. The main feature of this device was the lasing provided by tunnel injection of electrons and their radiative recombination with holes at the interface. Here we present a new advanced design of the tunnel-injection laser where high-operation temperature up to T=195 K was achieved in pulse regime.
