Efficient generation of optical bottle beams
Yuzhe Xiao, Zhaoning Yu, Raymond A. Wambold +5
Optical bottle beams can be used to trap atoms and small low-index particles. We introduce a figure of merit for optical bottle beams, specifically in the context of optical traps,…
Passive frequency conversion of ultraviolet images into the visible using perovskite nanocrystals
Jad Salman, Mahesh K. Gangishetty, Bryan E. Rubio-Perez +8
We demonstrate a passive down-conversion imaging system that converts broadband ultraviolet light to narrow-band green light while preserving the directionality of rays, and thus e…
Hyperspectral interference tomography of nacre
Jad Salman, Cayla A. Stifler, Alireza Shahsafi +12
Structural characterization of biologically formed materials is essential for understanding biological phenomena and their environment, and generating new bio-inspired engineering…
Adjoint-optimized nanoscale light extractor for nitrogen-vacancy centers in diamond
Raymond A. Wambold, Zhaoning Yu, Yuzhe Xiao +7
We designed a nanoscale light extractor (NLE) for efficient outcoupling and beaming of broadband light emitted by shallow, negatively charged nitrogen-vacancy (NV) centers in bulk…
Ultrathin broadband reflective optical limiter
Chenghao Wan, Zhen Zhang, Jad Salman +7
Optical limiters are nonlinear devices that feature decreasing transmittance with increasing incident optical intensity, and thus can protect sensitive components from high-intensi…
Guidelines for measurement of thermal emission
Yuzhe Xiao, Chenghao Wan, Alireza Shahsafi +7
Thermal emission is the radiation of electromagnetic waves from hot objects. The promise of thermal-emission engineering for applications in energy harvesting, radiative cooling, a…
