Electrically Pumped Mid‐Infrared Random Lasers
Advanced Materials, 2013 Electrically pumped random lasers, operating in the mid-infrared regime at λ ≈ 10 μm, are realized for the first time. Randomly distributed air holes are patterned onto a quantum cascade wafer emitting in the transverse-magnetic (TM) polarization. The advantage of employing TM polarized gain medium is that TM modes are more effectively confined in the ...
