Modulating optically active signals in a chiral metamaterial with varied input intensities
10:30-10:45
2017-10-04 10:30 2017-10-04 10:45 America/Denver Modulating optically active signals in a chiral metamaterial with varied input intensities Here we report an optical metamaterial with tailored chiroptical effects in the nonlinear regime, which exhibits a pronounced shift in its circular dichroism spectrum under a modest level of excitation power. Strong nonlinear optical rotation is observed at key spectral locations. Hilton Santa Fe Historic Plaza Kahiki/Lily

Control of Light-matter Interaction in 2D Semiconductors Invited
10:45-11:15
2017-10-04 10:45 2017-10-04 11:15 America/Denver Control of Light-matter Interaction in 2D Semiconductors We will discuss enhancement of spontaneous emission, formation of strongly coupled exciton-photon polaritons, valley polaritons and enhancement of nonlinear optical response from 2D transition metal dichalcogenides (TMD) embedded in microcavities, and photonic hypercrystals. Engineered single photon emission from hexagonal boron nitride will also be discussed. Hilton Santa Fe Historic Plaza Kahiki/Lily

Wideband resonant metasurfaces: Role of local modes
11:15-11:30
2017-10-04 11:15 2017-10-04 11:30 America/Denver Wideband resonant metasurfaces: Role of local modes We treat subwavelength resonant metasurfaces inscribed with 1D and 2D periodic patterning. We show that local Fabry-Perot modes or Mie modes are not fundamentally needed to achieve wideband response. In fact, device embodiments with such modes being absent yield wider bands.

Dielectric metasurfaces with independent angular control
11:30-11:45
2017-10-04 11:30 2017-10-04 11:45 America/Denver Dielectric metasurfaces with independent angular control We introduce dielectric metasurfaces with independent response at different angles of incidence given the same input polarization. We demonstrate a reflective metasurface grating with different effective grating pitches under two different incident angles, and a hologram that projects different images for different incidence angles.

Dispersion-controlled diffractive devices with dielectric metasurfaces
11:45-12:00
2017-10-04 11:45 2017-10-04 12:00 America/Denver Dispersion-controlled diffractive devices with dielectric metasurfaces Diffractive optical devices follow a negative chromatic dispersion dictated by device function. Here we show that metasurfaces with independent control of phase and group delays enable diffractive devices that break this relation. We demonstrate gratings and focusing mirrors with enhanced negative, zero, and positive dispersion. Hilton Santa Fe Historic Plaza Kahiki/Lily
