TuA2.1 - NONLINEAR METASURFACES FOR OPTICAL APPLICATIONS
Abstract
Abstract
Plasmonic and metamaterial systems are enabling to the generation, detection and conversion of single photons. We explore metasurface engineering for nonlinear response. A focus of our work is exploring novel materials systems that combine the functionality needed for nonlinear plasmonic metasurfaces and dynamic optical systems.
TuA2.2 - OPTICAL FREQUENCY TOPOLOGICAL PHOTONIC STRUCTURES
Abstract
Abstract
Topological photonic structures in analogy to their electronic counterparts can provide new functionalities in nanophotonics through topological protection. We will discuss design, fabrication and optical response of such topological photonic structures composed of photonic crystals (PhC) in silicon-on-insulator (SOI) systems operating around 1550nm wavelength.
TuA2.3 - LOW VOLUME IMAGING WITH METASURFACES
Abstract
Abstract
Volumetric Imaging Efficiency (VIE) compares the compactness and capacity of an imager against the limit imposed by diffraction. This metric is used to compare optical technologies for low-volume imaging and show that a combination of metasurface lenses can surpass the VIE limits of conventional imagers.
TuA2.4 - DESIGNING AND CHARACTERIZATING OF METALENSES FOR THE INCREASED LIGHT EXTRACTION OF MWIR LEDS
Abstract
Abstract
High radiance IRLEDs have been achieved, but much of the light created still remains in the device resulting in poor wall-plug efficiencies. Preliminary results presented here show increased light extraction by the addition of a 2D lens to the device, known as a metalens.
TuA2.5 - METASURFACE INTEGRATED MICROBOLOMETERS
Abstract
Abstract
This study reports on the integration of metasurfaces with microbolometers to provide spectral and/or polarized Long Wave Infrared selectivity. Metal antenna elements are in direct contact with SixGeyO1-x-y based microbolometers and modify the electrical/noise performance of the device in addition to engineering the electromagnetic response.
