We propose a dielectric grating with a metal slab with high efficiency for dense wavelength division multiplexing in optical communication. The g rating is a mixed structure of the fused silica grating and the Ag slab. For the special duty cycle of 0.65 and optimized grating depth and period, the grating can show the efficiency of 97.57% for TE polarization and 97.10% for TM polarization. Furthermore, it indicates that the wideband incident wavelength can be obtained from the analysis of performance. Most importantly, the good fabrication tolerance for efficiency higher than 95% can facilitate the fabrication and application of such a grating..

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.
