Electrically tunable VO2-metal metasurface for mid-infrared switching, limiting, and nonlinear isolation
Jonathan King, Chenghao Wan, Tae Joon Park +4
We demonstrate an electrically controlled metal-VO2 metasurface for the mid-wave infrared that simultaneously functions as a tunable optical switch, an optical limiter with a tunab…
Colossal optical anisotropy from atomic-scale modulations
Hongyan Mei, Guodong Ren, Boyang Zhao +17
In modern optics, materials with large birefringence (Δn, where n is the refractive index) are sought after for polarization control (e.g. in wave plates, polarizing beam splitters…
Metasurface-enhanced mid-infrared spectrochemical imaging of tissues
S. Rosas, K. A. Schoeller, E. Chang +5
Label-free and nondestructive mid-infrared vibrational hyperspectral imaging is emerging as an important ex-vivo tissue analysis tool, providing spatially resolved biochemical info…
