A three port p olarization independent beam splitter is described by the grating with a connecting layer between the grating region and the substrate. Such a novel diffractive three port beam splitter is optimi zed to achieve high diffraction efficiency with good uniformity. With the optimized grating para meters, efficiencies of 32.03%/ 32.06% and 32.14% 32.14%/32.15% can be separated into the 1st and the 0th orders for TE and TM polarizations, respectively. Besides, th e usual duty cycle of 0.5 and the aspect ratio of the grating depth to the ridge width of 1.83 facilitate the fabrication compared with reported gratings..

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.
