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…
Structurally Tunable Nonlinear Terahertz Metamaterials using Broadside Coupled Split Ring Resonators
George R. Keiser, Nicholas Karl, Sheikh Rubaiat Ul Haque +3
We present an experimental and numerical study of a terahertz metamaterial with a nonlinear response that is controllable via the relative structural positioning of two stacked spl…
Characterization of Suspended Membrane Waveguides towards a Photonic Atom Trap Integrated Platform
Michael Gehl, William Kindel, Nicholas Karl +10
We demonstrate an optical waveguide device, capable of supporting the high, in-vacuum, optical power necessary for trapping a single atom or a cold atom ensemble with evanescent fi…
Integrated optical addressing of a trapped ytterbium ion
M. Ivory, W. J. Setzer, N. Karl +6
We report on the characterization of heating rates and photo-induced electric charging on a microfabricated surface ion trap with integrated waveguides. Microfabricated surface ion…
