Quantum cascade laser with grating formed by a periodic variation in doping
摘要
<p>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.</p>
