Room temperature continuous wave operation of quantum cascade lasers with 12.5% wall plug efficiency
Y. Bai, S. Slivken, S. R. Darvish, and M. Razeghi
An InP based quantum cascade laser heterostructure emitting at 4.6 [mu]m was grown with gas-source molecular beam epitaxy. The wafer was processed into a conventional double-channel ridge waveguide geometry with ridge widths of 19.7 and 10.6 [mu]m without semi-insulating InP regrowth. An uncoated, ... [Appl. Phys. Lett. 93, 021103 (2008)] published Mon Jul 14, 2008.
