A novel design of reflective single-port polarization-independent grating with a metal mirror, a connection layer and a covering layer under second Bragg mounting is reported in this paper. A better grating structure by rigorous coupled-wave method can be obtained. The grating parameters are optimized for high-efficiency output. The optimization results show that in the wavelength range of 1546-1554 nm or the incident angle is between 38.0-39.3°, the -2nd order of the grating has a good high-efficiency output effect, and the efficiency can reach more than 90%, which will be a good application in the field of laser.

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.
