A two-layer three-port output grating with high-efficiency beam splitting is presented in this paper. The grating can split the incident wave into the 0th order and the ±1st orders for both TE and TM polarizations at the wavelength of 800 nm. According to the property of the incident angular bandwidth, the efficiency of every diffracted order exceeds 30% within the incident angular bandwidth range of -1.04-3.14°. Compared with the conventional reported single-layer three-port grating, the two-layer three-port grating has merits of not only the higher efficiency but also the broader angular bandwidth..

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.
