A novel design of reflective three port polarization dependent grating with a metal mirror and a connection layer under the second Bragg incidence is reported in this paper. C ompared with a desc ription of fused silica grating at the second Bragg angle, the grating diffraction efficiency for TE polarization is improved. Besides, the wide spectral bandwidth of 109 nm for TM polarization is obtained. Hence, the reflective three port grating has the advantages of the improvement of diffraction efficiencies for TE polarization and broad spectral bandwidth for TM 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.
