High reflectivity subwavelength metal grating for VCSEL applications

We report theoretical simulation of a novel silver subwavelength grating with reflectivity > 99.5%, substantially higher than uniform thin film, and a wide 99%-reflectivity bandwidth of 190nm, promising for VCSELs and surface-normal optoelectronic devices.
