  • Infrared subwavelength focusing in silicon and energy harvesting devices
    Patent number: 10948627
    Abstract: An infrared subwavelength metasurface lens implements slit width modulation focusing of infrared light into a subwavelength region located within a silicon substrate. The lens includes a metasurface deposited on a surface of the silicon substrate, where the metasurface has multiple discrete copper elements separated by uniformly distributed slits of different widths. The device may also implement refractive index modulation by filling different slits with silicon or air. The infrared subwavelength metasurface lens may be coupled with a thermoelectric generator to form a thermoelectric infrared harvesting device.
    Type: Grant
