In this paper, an all optical switch based on linear photonic crystal directional coupler, consists of three regions of input, coupling and output has been Simulated and analyzed in order to increase high speed and quality of switches. For this reason FDTD method has also been identified as the preferred method for performing electromagnetic simulations. We have tried to increase the coupling efficiency and reduce the required power in the linear statue. Therefore, the input signal beam can be controlled to be exchanged between two output ports to earn the highest output power. As a result, electric field intensity and the power output that are two important factors to improve the switching performance and the device efficiency. Where central row rods are (0.15a) and (0.16a), all optical directional coupler switches have been investigated and simulated by using COMSOL software..

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.
