The characteristics of spontaneous emission  amplified spontaneous emission and modal gain of the MQW is investigated by using single-pass multi-section technique. The amplified spontaneous emission is around a wavelength of 1500nm  dependent on the temperature and the current density. The modal gain spectra show a red shift with increasing temperature. The peak modal gain exhibits a decrease with increasing temperature from 140K to 300K. The loss measurements shows that the main loss mechanism in the structure might be the free carrier absorption in the doped cladding layers and a internal modal loss of about 10cm-1.   Progress of Si-based nanocrystalline luminescent materials 期刊论文  OAI收割 chinese science bulletin, 2002, 卷号: 47, 期号: 15, 页码: 1233-1242 Peng YC; Zhao XW; Fu GS 收藏  |  浏览/下载：109/0  |  提交时间：2010/08/12 Si-based nanomaterials  fabricated method  structural characterization  light emitting mechanism  Si-based photoelectronic devices  CHEMICAL-VAPOR-DEPOSITION  SELF-ASSEMBLING FORMATION  SILICON QUANTUM DOTS  LASER-ABLATION  OPTICAL-ABSORPTION  POROUS SILICON  LIGHT-EMISSION  PHOTOLUMINESCENCE  FABRICATION  OXYGEN   Extended quantum confinement luminescence center model for photoluminescence from oxidized porous silicon and nanometer-Si-particle- or nanometer-Ge-particle-embedded silicon oxide films 期刊论文  OAI收割 Materials Research Bulletin, 1998, 卷号: 33, 期号: 12, 页码: 1857-1866 G.
