Large tuning of the optical properties of nanoscale NdNiO3 via electron doping
Yeonghoon Jin, Teng Qu, Siddharth Kumar +6
We synthesized crystalline films of neodymium nickel oxide (NdNiO3), a perovskite quantum material, switched the films from a metal phase (intrinsic) into an insulator phase (elect…
Thermally-Switchable Metalenses Based on Quasi-Bound States in the Continuum
Stephanie C. Malek, Cheng-Chia Tsai, Nanfang Yu
Dynamic wavefront shaping with optical metasurfaces has presented a major challenge and inspired a large number of highly elaborate solutions. Here, we experimentally demonstrate t…
Metasurface Smart Glass for Object Recognition
Cheng-Chia Tsai, Xiaoyan Huang, Zhicheng Wu +2
Recent years have seen a considerable surge of research on developing heuristic approaches to realize analog computing using physical waves. Among these, neuromorphic computing usi…
Leaky-wave metasurfaces for integrated photonics
Heqing Huang, Adam C. Overvig, Yuan Xu +4
Metasurfaces have been rapidly advancing our command over the many degrees of freedom of light within compact, lightweight devices. However, so far, they have mostly been limited t…
Physical and Behavioral Adaptations to Prevent Overheating of the Living Wings of Butterflies
Cheng-Chia Tsai, Richard A. Childers, Norman Nan Shi +5
The wings of Lepidoptera contain a matrix of living cells whose function requires appropriate temperatures. However, given their small thermal capacity, wings can overheat rapidly…
Nanophotonic Filters and Integrated Networks in Flexible 2D Polymer Photonic Crystals
Xuetao Gan, Hannah Clevenson, Cheng-Chia Tsai +2
Polymers have appealing optical, biochemical, and mechanical qualities, including broadband transparency, ease of functionalization, and biocompatibility. However, their low refrac…
Light trapping in a 30-nm organic photovoltaic cell for efficient carrier collection and light absorption
Cheng-Chia Tsai, Richard R. Grote, Ashish Banerjee +2
We describe surface patterning strategies that permit high photon-collection efficiency together with high carrier-collection efficiency in an ultra-thin planar heterojunction orga…
Directional free-space coupling from photonic crystal waveguides
Cheng-Chia Tsai, Jacob Mower, Dirk Englund
We present a general approach for coupling a specific mode in a planar photonic crystal (PC) waveguide to a desired free-space mode. We apply this approach to a W1 PC waveguide by…
