Based on the coupled mode theory, by using the time-domain transfer matrix method, the bistable performance and dynamic switching characteristics of linear tapered nonlinear Bragg gratings (LT-NLBG) are analyzed numerically. We consider both the positive and negative tapered case and compare their performance as a nonlinear switch. The results show that, With the quasi-continuous wave taken into consideration, for the various tapered factors, the temporal characteristics exists with significant difference, including output self-pulsation amplitude, time delay and pulse-width, etc.; As a short pulse switching device, the positive tapered gratings display much less splitting, an indication that modulation instability is not playing a significant role, and the transmitted pulse is much more intense than that in the negative tapered case..

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.
