Wasatch Photonics

Diffraction gratings that operate in transmission can be used for many different applications, providing high efficiency, low stray light, and a range of dispersion options from 150-5000 lines/mm and operating at wavelengths 300-2500 nm. They also enable more compact, lens-based designs. Here, we review the top 5 most popular applications we see at Wasatch Photonics, and how our VPH transmission gratings excel at each.

New Imaging Technology

Nanocrystals are semiconductor nanoparticles whose optical properties can be tuned from UV up to THz. They are used as sources of green and red light for displays, and also show exhibit promises to design low-cost infrared detectors. Coupling subwavelength optical resonators to nanocrystals film enables to design photodiodes that absorb 80% of incident light from thin (<150 nm) nanocrystal film. It thus becomes possible to overcome the constraints linked to the short diffusion lengths which result from transport by hopping within arrays of nanocrystals enabling high photoresponse detector operating in the SWIR range.
