Enhanced biochemical sensing with high-Q transmission resonances in free-standing membrane metasurfaces
Samir Rosas, Wihan Adi, Aidana Beisenova +7
Optical metasurfaces provide novel solutions to label-free biochemical sensing by localizing light resonantly beyond the diffraction limit, thereby selectively enhancing light-matt…
Preventing overfitting in infrared ellipsometry using temperature dependence: fused silica as a case study
Shenwei Yin, Jin-Woo Cho, Demeng Feng +6
Fitting oscillator models to variable-angle spectroscopic ellipsometry (VASE) data can lead to non-unique, unphysical results. We demonstrate using temperature-dependent trends to…
Atomic magnetometry using a metasurface polarizing beamsplitter in silicon on sapphire
Xuting Yang, Pritha Mukherjee, Minjeong Kim +9
We demonstrate atomic magnetometry using a metasurface polarizing beamsplitter fabricated on a silicon-on-sapphire (SOS) platform. The metasurface splits a beam that is near-resona…
Self-referencing photothermal common-path interferometry to measure absorption of Si3N4 membranes for laser-light sails
Tanuj Kumar, Demeng Feng, Shenwei Yin +12
Laser-light sails are a spacecraft concept wherein lightweight "sails" are propelled by high-intensity lasers. We investigated the near-infrared absorption of free-standing membran…
Molten flux growth of single crystals of quasi-1D hexagonal chalcogenide BaTiS3
Huandong Chen, Shantanu Singh, Hongyan Mei +7
BaTiS3, a quasi-1D complex chalcogenide, has gathered considerable scientific and technological interest due to its giant optical anisotropy and electronic phase transitions. Howev…
Infrared Optical Anisotropy in Quasi-1D Hexagonal Chalcogenide BaTiSe3
Boyang Zhao, Hongyan Mei, Zhengyu Du +9
Polarimetric infrared detection bolsters IR thermography by leveraging the polarization of light. Optical anisotropy, i.e., birefringence and dichroism, can be leveraged to achieve…
Trapping light in air with membrane metasurfaces for vibrational strong coupling
Wihan Adi, Samir Rosas, Aidana Beisenova +4
Optical metasurfaces can manipulate electromagnetic waves in unprecedented ways at ultra-thin engineered interfaces. Specifically, in the mid-infrared (mid-IR) region, metasurfaces…
