Modulators Using DPS-DNG-Layered Structure

摘要

The influence of an applied electric field on a periodic structure composed of alternating layers of isotropic DPS (double positive index of refraction) and anisotropic DNG (double negative index of refraction) has been studied and shown that in the presence of an external electric field, one can convert the polarization state of the incident electromagnetic wave into a desired polarization state, change the phase and amplitude, and induce birefringence. Here, theoretical and numerical results of investigation of phase and amplitude modulator in the presence of an applied electric field are presented.
