The transparency threshold has been obtained at photon energy of 0.8016 eV and at zero normalized applied transition energy, respectively. The modal gain of about 12.5 cm-1 is obtained at the threshold current density of 51 Acm-2. The external differential quantum efficiency of 65% has been achieved for the cavity length of 640 μm. The proposed structure with acceptable enhanced results will create a way to fabricate InN based quantum dot laser. 2014-04-30T01:58:10Z 2014-04-30T01:58:10Z 2013-08 Article Proceedings of SPIE - The International Society for Optical Engineering, vol. 8883, 2013, pages 978-081949666-9 0277-786X http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=1745135 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34183 en The International Society for Optical Engineering (SPIE) |
