A DCM laser dye doped Alq film serves as the active layer. High reflective and low loss electrical contacts are used to form a high quality factor coupled microcavity. Single longitudinal cavity mode is obtained at 618 nm with a threshold current density of 612 mAcm-2 under room temperature continuous wave operation. 2012 SPIE.   Theoretical analysis of emission characteristics of second-order distributed feedback semiconductor lasers (EI CONFERENCE) 会议论文  OAI收割 Semiconductor Lasers and Applications IV, October 18, 2010 - October 19, 2010, Beijing, China 作者:  Liu Y.;  Liu Y.;  Qin L.;  Liu Y.;  Wang L. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 Based on the modified coupled-wave theory  the emission characteristics  including threshold gain  photon density distribution in the cavity  and external differential quantum efficiency for second-order DFB lasers are investigated. Numerical simulation results show that for given device structure with wavelength of 1.55 m  the feedback coupling coefficient and the surface radiation coupling coefficient of the second-order grating have great influence on the emission characteristics of the device. By choosing different duty cycles of the grating  we can change the two coupling coefficients  which affect the emission characteristics. For an overall consideration  an optimal duty cycle of 0.43 is chosen. The optimized results show that the device works without degeneracy modes and spatial burning hole. Besides  the side-mode suppress ratio (SMSR) and external differential quantum efficiency reach as high as 42 dB and 47%  respectively. 2010 SPIE.   The optical gain and radiative current density of GaInNAs/GaAs/AlGaAs separate confinement heterostructure quantum well lasers 期刊论文  OAI收割 Journal of Applied Physics, 2010, 卷号: 107, 期号: 1 S.
