Optical devices with metastable states controlled with light (optical flip-flops) are needed in data storage, signal processing and displays. Although non-volatile optical memory relying on structural phase transitions in chalcogenide glasses has bee

A profound optical bistability in light scattering is observed in a pair of oscillating nanowires decorated with plasmonic patterns. The response becomes bistable at only a few μW of incident optical power, which is facilitated by coupling between t

We experimentally observe that fluctuations in metamaterial optical properties peak at the frequencies of the nanostructures’ natural mechanical modes, due to ‘Brownian’ motion. Fluctuations in flexural phonon density are the underlying mechani

This Thesis reports on the study of hybrid nano-optomechanical metamaterials, and their sensing, nonlinear and switching functionalities.I have constructed a dedicated apparatus for optical measurements of photonic metamaterials in vacuum during acou

We demonstrate that fluctuations in the optical properties of nanomechanical photonic metamaterials can reach 1% at room temperature. Such fluctuations arise from ‘Brownian’ motion and peak at the frequencies of the nanostructures’ natural mech
