Most optical components can be grouped under the umbrella of "bulk optics"; i.e. they generally have a non-negligible thickness compared to the wavelength of light. This is the case for prisms, lenses, etc., all of which must be of sufficient thickness such that light accumulates a substantial amount of optical phase upon propagation.
In this talk, I will describe our development of optical components based on plasmonics that are flat and thin compared to the wavelength of light. We explore approaches to redirect, and reshape, absorb, and emit light with ultra-thin plasmonic structures which are easy to fabricate with conventional micro- and nanofabrication techniques. Furthermore by incorporating materials with widely-tunable optical properties such as vanadium oxide and graphene into these ultra-thick components we can create dynamically reconfigurable optical elements operating at nanosecond time scales.
