Guided-mode triggered switching between TE orders of a metal-based grating-waveguide

An undulated metal-based dielectric slab waveguide is shown to exhibit a high contrast broadband switching effect in the angular spectrum between the 0 th order Fresnel reflection and the propagating -1 st reflected diffraction orders. The switching trigger is the synchronous collinear coupling of a...

Summary:An undulated metal-based dielectric slab waveguide is shown to exhibit a high contrast broadband switching effect in the angular spectrum between the 0 th order Fresnel reflection and the propagating -1 st reflected diffraction orders. The switching trigger is the synchronous collinear coupling of an incident TE plane wave to the close-to-cutoff forward- and backward-propagating fundamental TE 0 mode of the waveguide via the +1 st and -2 nd order of the periodic undulation.
