Long-Wave IR Quantum Cascade Lasers for emission in the [lambda] = 8-12 mu m spectral region

In this article we review a selection of recent results on long-wave quantum cascade lasers both for high power and for single-mode emission. Both MBE-grown and MOCVD-grown devices are examined and compared. Currently, LWIR QC lasers exhibit output powers in the Watt-level range and up to double-dig...

Summary:In this article we review a selection of recent results on long-wave quantum cascade lasers both for high power and for single-mode emission. Both MBE-grown and MOCVD-grown devices are examined and compared. Currently, LWIR QC lasers exhibit output powers in the Watt-level range and up to double-digit conversion efficiencies in the best cases.
