| 摘 要： | 窄带宽的AlGaAs/GaAs布拉格光栅耦合到InP的半导体量子级联激光器从而产生稳定的激光频谱,其激光谱线宽度在1纳米左右.如果不加光栅,非稳定的自由激射的激光器的谱线宽度有30 nm左右.隔离的分布式布拉格光栅可以独立调谐几个纳米.

| Abstract: | Narrow-bandwidth AlGaAs/GaAs Bragg grating was externally coupled with InP semiconductor based quantum cascade laser to yield stable wavelength operation with 1 nm linewidth, compared to unstable, multi-line spectra with 30 nm span of the free-running device. Isolated DBR segment allowed wavelength tuning of a few nm independently from the gain element. |
