摘要:

利用Synopsys公司的Sentaurus TCAD软件进行了计算机模拟,研究了有源区和波导区中铝的摩尔浓度对AlxGa 1-xAs双异质结和单独限制(SCH)半导体激光器量子阱中载流子能谱和辐射光谱特性的影响。单模激光器的波长在很宽的铝含量范围内几乎与波导中铝的浓度无关,但在QW区主要取决于铝的浓度。

英文摘要:

Computer simulations with Synopsys' Sentaurus TCAD are used to study the effect of the molar concentration of aluminum in the active and waveguide regions on the energy spectrum of carriers in Quantum Well (QW) and the optical spectral characteristics of radiation of semiconductor lasers with AlxGa1-xAs double heterostructures and separate confinement (SCH). Wavelength of single-mode lasers is shown to be almost independent of the concentration of aluminum in the waveguide, in a wide range of aluminum content, but to depend mainly on Al concentrations in QW region.
