Abstract
Behaviors of chirped DBR for group velocity dispersion (GVD) compensation in THz QCLs with metal-metal waveguides have been investigated theoretically in both 1D and 3D models with COMSOL Multiphysics. The strategy of designing chirped DBR for GVD compensation in terahertz frequency range has been presented. In order to achieve broad-band GVD compensation with less distortion, a two-section chirped DBR structure is proposed.
