Abstract

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.
