Broadband Thermal Imaging using Meta-Optics
Luocheng Huang, Zheyi Han, Anna Wirth-Singh +13
Subwavelength diffractive optics known as meta-optics have demonstrated the potential to significantly miniaturize imaging systems. However, despite impressive demonstrations, most…
Gate-Tunable Optical Anisotropy in Wafer-Scale, Aligned Carbon-Nanotube Films
Jason Lynch, Evan Smith, Adam Alfieri +10
Telecommunications and polarimetry both require the active control of the polarization of light, Currently, this is done by combining intrinsically anisotropic materials with tunab…
High Density, Localized Quantum Emitters in Strained 2D Semiconductors
Gwangwoo Kim, Hyong Min Kim, Pawan Kumar +14
Two-dimensional chalcogenide semiconductors have recently emerged as a host material for quantum emitters of single photons. While several reports on defect and strain-induced sing…
Photonic Integrated Circuit for Rapidly Tunable Orbital Angular Momentum Generation Using Sb2Se3 Ultra-Low-Loss Phase Change Material
MD Shah Alam, Rudra Gnawali, Joshua R. Hendrickson +4
The generation of rapidly tunable Optical Vortex (OV) beams is one of the most demanding research areas of the present era as they possess Orbital Angular Momentum (OAM) with addit…
Chiral Phase Change Nanomaterials
Joshua A. Burrow, Md Shah Alam, Evan M. Smith +8
Chiral nanostructures offer the ability to respond to the vector nature of a light beam at the nanoscale. While naturally chiral materials offer a path towards scalability, enginee…
Steady-state nonlinear optical response of excitons in monolayer MoSe
Muhed S. Rana, Joshua R. Hendrickson, Christopher E. Stevens +7
Monolayer transition metal dichalcogenide (TMD) semiconductors such as MoSe host strongly bound excitons which are known to exhibit a strong resonant third-order nonlinear resp…
Phase change dynamics and 2-dimensional 4-bit memory in Ge2Sb2Te5 via telecom-band encoding
Gary A. Sevison, Shiva Farzinazar, Joshua A. Burrow +8
As modern computing gets continuously pushed up against the von Neumann Bottleneck -- limiting the ultimate speeds for data transfer and computation -- new computing methods are ne…
Improving the performance of GeSbTe materials via nickel doping: Towards RF-compatible phase-change devices
Pengfei Guo, Joshua A. Burrow, Gary A. Sevison +6
High-speed electrical switching of Ge2Sb2Te5 (GST) remains a challenging task due to the large impedance mismatch between the low-conductivity amorphous state and the high-conducti…
Experimental Observation of Strong Coupling Between an Epsilon-Near-Zero Mode in a Deep Subwavelength Nanofilm and a Gap Plasmon Mode
Joshua R. Hendrickson, Shivashankar Vangala, Chandriker K. Dass +6
Strong coupling is a phenomenon which occurs when the interaction between two resonance systems is so strong that the oscillatory energy exchange between them exceeds all dissipati…
Subwavelength metal grating metamaterial for polarization selective optical antireflection coating
Wonkyu Kim, Junpeng Guo, Joshua Hendrickson
A metamaterial structure consisting of a one-dimensional metal/air-gap subwavelength grating is investigated for optical antireflection coating on germanium substrate in the infrar…
Multi-spectral near perfect metamaterial absorbers using spatially multiplexed plasmon resonance metal square structures
Boyang Zhang, Joshua Hendrickson, Junpeng Guo
Near perfect infrared light absorption at multi-spectral wavelengths has been experimentally demonstrated by using multiplexed metal square plasmon resonance structures. Optical po…
A wide-band perfect light absorber at mid-wave infrared using multiplexed metal structures
Joshua Hendrickson, Junpeng Guo, Boyang Zhang +2
We experimentally demonstrate a wide band near perfect light absorber in the mid-wave infrared region using multiplexed plasmonic metal structures. The wide band near perfect light…
Arrays of Ag split-ring resonators coupled to InGaAs single-quantum-well gain
Nina Meinzer, Matthias Ruther, Stefan Linden +6
We study arrays of silver split-ring resonators operating at around 1.5-μm wavelength coupled to an MBE-grown single 12.7-nm thin InGaAs quantum well separated only 4.8 nm from the…
