Paper Abstract

Plasmonic has demonstrated the ability to enhance performances of photodetectors at a resonant wavelength. Absorption in a photodetector can reach 100% using nanophotonic plasmonic array. Plasmonic devices are confining light at the interface metal/dielectric, as a consequence, detection volume is smaller (100 to 1000 times) than in usual photodetectors leading to a decrease in dark current of infrared photodetectors and therefore a higher working temperature. The second consequence of a short detection volume is a higher collection efficiency of photocarriers as the transit time is smaller than the lifetime.
