Broadband frequency translation through time refraction in an epsilon-near-zero material

Here, the authors present an experimental demonstration of adiabatic frequency conversion using the concept of time boundary by exploiting the properties of an ITO film operating near its epsilon-near-zero frequency. They demonstrate a large and controllable shift up to 14.9 THz.

Strong coupling between distant photonic nanocavities and its dynamic control

Scientists demonstrate strong coupling between distant nanocavities separated by more than 100 wavelengths as well as dynamic control over the coupling state. The strong coupling state can be stopped on demand by irradiating one of the nanocavities with a control pulse, thus freezing the photon state.

Large optical nonlinearity of nanoantennas coupled to an epsilon-near-zero material

Enhanced nonlinear response of 50-nm-thick antennas in the vicinity of an epsilon-near-zero material enable an optically induced refractive index change of ±2.5 over a 200 nm spectral range.

Ultra-high-Q resonances in plasmonic metasurfaces

Metallic nanostructures are useful in many optical devices due to their nonlinear properties and responses to interaction with light. Here the authors demonstrate a metasurface of gold nanoparticle arrays with ultra-narrow surface lattice resonances of high quality-factor that operates in the telecommunication band.
