Wavelength-by-wavelength temperature-independent thermal radiation utilizing an insulator-metal transition
Jonathan King, Alireza Shahsafi, Zhen Zhang +7
Both the magnitude and spectrum of the blackbody-radiation distribution change with temperature. Here, we designed the temperature-dependent spectral emissivity of a coating to cou…
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…
Correcting thermal-emission-induced detector saturation in infrared reflection or transmission spectroscopy
C. Yao, H. Mei, Y. Xiao +7
We found that temperature-dependent infrared spectroscopy measurements (i.e., reflectance or transmittance) using a Fourier-transform spectrometer can have substantial errors, espe…
Planck spectroscopy
Yuzhe Xiao, Chenghao Wan, Jad Salman +4
All spectrometers rely on some mechanism to achieve spectral selectivity; common examples include gratings, prisms, and interferometers with moving mirrors. We experimentally demon…
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…
Infrared polarizer based on direct coupling to surface-plasmon polaritons
A. Shahsafi, J. Salman, B. E. Rubio Perez +3
We propose a new type of reflective polarizer based on polarization-dependent coupling to surface-plasmon polaritons (SPPs) from free space. This inexpensive polarizer is relativel…
