Broadband high-contrast-grating-type waveplates for the terahertz range

Surya Revanth Ayyagari, Andreas K Klein, Simonas Indrišiūnas, Vytautas Janonis, Daniil Pashnev, Abdu Subahan Mohammed, Guillaume Ducournau, Andreas Stöhr, Irmantas Kašalynas

The high-contrast-grating waveplates utilizing high contrast between silicon and air refractive indexes were developed in order to perform as a quarter wave and a half wave plate in the selected THz frequency range. The waveplates possessed anti-reflective properties due to the specific inclination...
