Near-field Imaging of Optical Resonances in Silicon Metasurfaces Using Photoelectron Microscopy
Alex Boehm, Sylvain D. Gennaro, Chloe F. Doiron +5
Precise control of light-matter interactions at the nanoscale lies at the heart of nanophotonics. Experimental examination at this length scale is challenging, however, since the c…
Sub picosecond steering of ultrafast incoherent emission from semiconductor metasurfaces
Prasad P. Iyer, Nicholas Karl, Sadhvikas Addamane +3
The ability to dynamically steer fs pulses from a monolithically integrated source is a critical milestone for the fields of nanophotonics and ultrafast optics. The nascent field o…
Cascaded optical nonlinearities in dielectric metasurfaces
Sylvain D. Gennaro, Chloe F. Doiron, Nicholas Karl +3
Since the discovery of the laser, optical parametric nonlinearities have been at the core of efficient light conversion sources. Typically, thick transparent crystals or quasi-phas…
High-harmonic generation from an epsilon-near-zero material
Yuanmu Yang, Jian Lu, Alejandro Manjavacas +7
High-harmonic generation (HHG) from a compact, solid-state medium is highly desirable for applications such as coherent attosecond pulse generation and extreme ultra-violet (EUV) s…
An optical metamixer
Sheng Liu, Polina P. Vabishchevich, Aleksandr Vaskin +5
A frequency mixer is a nonlinear device that combines electromagnetic waves to create waves at new frequencies. Mixers are ubiquitous components in modern radio-frequency technolog…
Active tuning of high-Q dielectric metasurfaces
Matthew Parry, Andrei Komar, Ben Hopkins +7
We demonstrate the active tuning of all-dielectric metasurfaces exhibiting high-quality factor (high-Q) resonances. The active control is provided by embedding the asymmetric silic…
