High-Q, size-independent, and reconfigurable optical antennas via zero-index material dispersion engineering
Prasad P. Iyer, Mihir Pendharkar, Anchal Agrawal +8
Enhancing light-matter interactions at the nanoscale is foundational to nanophotonics, with epsilon near zero (ENZ) materials demonstrating significant potential.High-quality (Q) f…
Terahertz pulse generation with binary phase control in non-linear InAs metasurface
Hyunseung Jung, Lucy L. Hale, Sylvain D. Gennaro +9
The effect of terahertz (THz) pulse generation has revolutionized broadband coherent spectroscopy and imaging at THz frequencies. However, THz pulses typically lack spatial structu…
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…
Unidirectional Luminescence from Quantum Well Metasurfaces
Prasad P. Iyer, Ryan A. DeCrescent, Nikita A. Butakov +6
III-Nitride light emitting diodes (LEDs) are the backbone of ubiquitous lighting and display applications. Imparting directional emission is an essential requirement for many LED i…
Beam engineering for selective and enhanced coupling to multipolar resonances
Tanya Das, Prasad P. Iyer, Jon A. Schuller
Multipolar electromagnetic phenomena in sub-wavelength resonators are at the heart of metamaterial science and technology. In this letter, we demonstrate selective and enhanced cou…
