Abstract :
Low threshold current density (Jth=65 A/cm2) operation near 1.3 μm at room temperature (RT) is realised for lasers using InAs-InGaAs-GaAs quantum dots (QDs). The lasing occurs via the QD ground state for cavity length L>1 mm. The differential efficiency is 40% and internal losses are 1.5 cm. The characteristic temperature near RT is 160 K.
