Abstract
This talk will report on the use of two different photoswitch-containing polymers for metasurface resonance tuning. Each photoswitch can be independently coated on a metasurface, and induce either red- or blueshifts in the metasurface resonance. However, the disparate wavelength tuning of the two photoswitches means they can also be used in combination. We demonstrate that light-responsive photoswitches can be employed alone, or in combination with other stimuli, to add advanced functionality to metasurface resonance tuning and enable potential applications in logic processing or optical neural networks.
