Abstract

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 a high photoresponse detector operating in the SWIR range
