Microring quantum cascade surface emitting lasers by David Stark, Mattias Beck, Jérôme Faist

“…We miniaturize a vertically coupled in-plane whispering gallery mode cavity incorporating a quantum cascade gain medium, aiming to realize the mid-infrared counterpart to the vertical cavity surface emitting laser. Building on previous work with linear microcavities, we introduce a new type of quantum cascade surface emitting laser (QCSEL) by miniaturizing a buried heterostructure ring cavity. …”
