This paper reports a new generalized dispersion equation and a intersection between the real parts of effective propagation constants for TE0 and TM0 and TE1 and TM1 modes as a function of number of glass layers in a multiple superconducting quantum well optical waveguide where the lossless glass layers have refractive index lower than that of the lossy superconducting layers. For the imaginary parts of the effective propagation constants, the intersections appear between TE0, TE1, TE2 modes or between TM0, TM1, TM2 modes. An increase in number of the quantum well, which is equivalent with an increase in refractive index, leads to a tighter confinement of the TE and TM modes to the core region.

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.
