英文摘要	we demonstrate room temperature operation of photonic-crystal distributed-feedback quantum cascade lasers emitting at 4.7 mu m. a rectangular photonic crystal lattice perpendicular to the cleaved facet was defined using holographic lithography. the anticrossing of the index- and bragg-guided dispersions of rectangular lattice forms the band-edge mode with extended mode volume and reduced group velocity. utilizing this coupling mechanism, single mode operation with a near-diffractive-limited divergence angle of 12 degrees is obtained for 33 mu m wide devices in a temperature range of 85-300 k. the reduced threshold current densities and improved heat dissipation management contribute to the realization of devices' room temperature operation.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-04-13t14:20:37z no. of bitstreams: 1 room temperature operation of photonic-crystal distributed-feedback quantum cascade lasers with single longitudinal and lateral mode performance.pdf: 453666 bytes, checksum: 703b35c3bd801c8701490f001e68fa0f (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-04-13t14:31:14z (gmt) no. of bitstreams: 1 room temperature operation of photonic-crystal distributed-feedback quantum cascade lasers with single longitudinal and lateral mode performance.pdf: 453666 bytes, checksum: 703b35c3bd801c8701490f001e68fa0f (md5); made available in dspace on 2010-04-13t14:31:14z (gmt). no. of bitstreams: 1 room temperature operation of photonic-crystal distributed-feedback quantum cascade lasers with single longitudinal and lateral mode performance.pdf: 453666 bytes, checksum: 703b35c3bd801c8701490f001e68fa0f (md5) previous issue date: 2010; national research projects of china 60525406 60736031 60806018 60906026 2006cb604903 2007aa03z446 2009aa03z403; 其它
