Multilevel leaky-mode optical elements, including reflectors, polarizers, and beamsplitters. Some of the elements have a plurality of spatially modulated periodic layers coupled to a substrate. For infrared applications, the optical elements may have a bandwidth larger than 600 nanometers.

Multilevel leaky-mode resonant optical devices

A leaky-mode resonant retarder is described. The retarder may include a substrate and a spatially modulated periodic layer coupled to the substrate, where the spatially modulated periodic layer is configured to shift a phase between two perpendicular electric-field components of incident light. The retarder may operate as a half-wave plate or a quarter-wave plate.

Leaky-mode resonant retarders and related methods

A method for delaying transmitted light. The method may include illuminating a leaky-mode resonant element with light pulses of short duration and sequences of such pulses. The leaky-mode resonant element may include a spatially modulated periodic layer and may be configured so that at least some of the light is transmitted in a delayed manner.
