掺杂和In组分对长波长III族氮化物量子点增益的影响

Effect of doping and In-composition on gain of long wavelength III-nitride QDs

摘要:

在这项工作中,我们计算长波长III族氮化物InN和AlInN量子点(QD)结构的材料增益。计算中包括应变和QD不均匀性。该研究覆盖了在光通信中重要的波长范围(800-2300 nm)。虽然p型掺杂被证明是有效的增加增益,改变量子点的大小(特别是量子点半径)是更有效地改变波长。结果表明,n掺杂量子点结构有望在宽带激光器中得到应用。

英文摘要:

In this work, we calculate material gain for long wavelength III-nitride InN and AlInN quantum dot (QD) structures. Strain and QD inhomogeneity are included in the calculations. The study covers (800-2300 nm) wavelength range which is important in optical communications. While p-doping is shown to be efficient to increasing gain, changing QD size (especially QD radius) is more efficient to vary wavelength. The results predicted that n-doped QD structures are promises for broad band laser applications.
