量子级联激光器光栅由掺杂的周期性变化形成

Quantum cascade laser with grating formed by a periodic variation in doping
摘要：
Doped diffraction gratings for use in quantum cascade lasers and mid-infrared wavelength vertical cavity surface emitting lasers can be made by introducing periodic variations in the doping levels that result in periodic refractive index variations. Doping is typically accomplished by use of an n type dopant.
摘要（中）：

用于量子级联激光器和中红外波长垂直腔面发射激光器的掺杂衍射光栅可以通过引入导致周期性折射率变化的掺杂水平的周期性变化来制造。 通常通过使用n型掺杂剂来实现掺杂。
