摘要	A saturable absorber (SA) based on a high-contrast grating (HCG) having a buried layer of quantum structures for absorption, and which is particularly well suited for use in a mode-locked application. The HCG-SA provides three times the bandwidth compared with traditional DBR structures, while exhibiting a lower saturation fluence due to the field enhancement inside the grating. Varying grating bar width over one or two axis provides lensing effects on the optical output, while chirping of the period and duty cycle changes optical phase relationships. Novel VCSEL embodiments with external or internal cavities are described using the HCG-SA.
其他摘要	一种基于高对比度光栅（HCG）的可饱和吸收体（SA），其具有用于吸收的掩埋量子结构层，并且特别适用于锁模应用。与传统的DBR结构相比，HCG-SA提供三倍的带宽，同时由于光栅内的场增强而表现出较低的饱和能量密度。在一个或两个轴上改变光栅条宽度对光输出提供透镜效应，而周期和占空比的啁啾改变光学相位关系。使用HCG-SA描述了具有外腔或内腔的新型VCSEL实施例。
