Abstract
We report room-temperature operation of £f?3.7£gm lattice-matched InGaAs/AlInAs/InP quantum cascade lasers based on frequency doubling with ?2mW/W 2 conversion efficiencies. Similar devices based on 1% strain-compensated materials can operate at £f=3-3.7£gm. ?2009 Optical Society of America.
