The three-port grating with a connecting slab under the second Bragg incidence is introduced in this paper. In order to improve bandwidth, in the case of a given duty cycle of 0.6, grating structure is described so that the three grating diffraction orders are with efficiencies over 30%, where bandwidths are 91 nm and 24 nm for TE and TM polarizations, respectively. For the optimized optimal solution, we can use the modal method to explain the physical process of grating diffraction..

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.
