Paper Abstract

The primary objective of this investigation was to analytically determine the effect of a plane dielectric interface upon the radiation loss of a curved channel dielectric wave-guide embedded in a dense substrate as commonly encountered in millimeter and optical integrated circuits. Results of our study indicate that in contrast to the case of a bent channel guide embedded in a homogeneous medium with an algebraic behavior of R0-1/2 (R0 is the radius of curvature of the bent channel guide), the radiation of a bent channel guide embedded below a plane dielectric interface exhibits an R0-3/2 dependence. This altered algebraic dependence can result in significant reductions in radiation loss.
