Abstract: Optical microscopy is limited to shallow interrogation depths as high-resolution imaging in scattering media is challenging. Current methods require complex and expensive experimental setup or suffer from low resolution. Through gating of photons exiting the… read more here.

Abstract: An all-dielectric double-layer grid grating is proposed and demonstrated theoretically and experimentally to realize the angular filtering effect. The theoretical results show that the transmission of the double-layer grid grating drops sensitively, as the incident… read more here.
