Issue Date: | 2012 | Source: | Meng, B., & Wang, Q. (2012). Quantum cascade lasers of λ ≈ 14µm based on three-phonon-resonance design. 2012 Photonics Global Conference (PGC). | Abstract: | We report the design and demonstration of ~14 μm quantum cascade lasers based on the three-phonon-resonance active region design. The as-cleaved device with 40 periods of active region and size of 3.8 mm×28μm shows ~10 mW peak power at 280 K and maximum working temperature of 295 K. Due to the Stark effect, the laser wavelength blue-shifts from 13.75 to 13.4 μm for temperature changing from 200 K to 295 K at around roll-over current density, with characteristics temperature of 440 K. | URI: | https://hdl.handle.net/10356/97832 http://hdl.handle.net/10220/12202 |
