Nonmetallic Broadband Visible-Light Absorbers With Polarization and Incident Angle Insensitivity

We have proposed and theoretically analyzed nonmetallic broadband visible-light absorbers based on alternating SiO 2 /InAs thin films on SiO 2 substrate. Compared with the conventional absorbers, the proposed SiO 2 /InAs structure can achieve excellent absorption within a smaller volume. The average...
