Description

The perfect absorption of light in subwavelength thickness layers generally relies on exotic materials, metamaterials, or thick metallic gratings. Here we demonstrate that total light absorption can be achieved in ultrathin gratings composed of conventional materials, including relatively weakly absorbing semiconductors, which are compatible with optoelectronic applications such as photodetectors and optical modulators. We fabricate a 41 nm thick antimony sulphide grating structure that has...[Show more]
