We theoretically design the plasmonic structures based on the coupling between the graphene sheets and resonators for the mid IR region, which can be used to construct the ultra compact fast tunable optical filter, splitter, 1×2 digital optical switch, or Mach Zehnder interferometer. Electric al tunability of the system by tiny change of the Fermi level (chemical potential) of the graphene is realized In addition the quality and sensitivity of the system can be optimized by changing the coupling distance The finite element method results are verified by the resonance theory of the rings..

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.
