Abstract

Hereby, we present analysis of threshold generation in DFB laser based on isotropic medium with optical gain and hyperbolic metamaterial (HMM) forming together a periodic structure, namely photonic hypercrystal. We investigate possibility of controlling threshold modal spectrum enabled by exploiting dispersion of the HMM structure. For this purpose, we developed an original approach for threshold generation analysis based on modified transfer matrix method. We demonstrate that, changing the dispersion type of HMM medium, may lead to a number of interesting effects, such as generation of single-mode, controllable side-mode suppression or ultra-low generation threshold.
