A phase grating with a connecting layer is proposed for reflective splitter with high efficiency. A fused-silica layer and a metal slab are between the grating region and the substrate, which are different from the conventional grating directly etched in material. The grating parameters are optimized by numerical simulation, including the grating depth and connecting layer thickness. The reflective beam splitter can have merits of high efficiency and wideband property to some extent, especially for TE polarization..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
