Concentric tubes silicon-based metamaterial structure for mid-IR broadband absorption

In this work, we are proposing a silicon (Si) based concentric tube broadband absorber. The proposed broadband absorber is composed of consecutive concentric tubes of intrinsic Si and doped-Si (D-Si) layers. The structure exhibits a broadband performance within a wide range of mid-IR wavelength spectrum extending from 3 to 7 µm with an absorption peak that varies between 0.88 and 0.97 in the case

Non-reciprocal Devices Using Time Dependent Materials

This work targets an optical analogue for the electronic diode that is the cornerstone and one of the main reasons behind the diversity, maturity, and applicability of the field of electronics. In this work, we exploit intermodal coupling within spatio-temporally modulated systems to induce coupling between modes whose group velocities attain opposite signs. We analytically prove that when
