Potential of Periodic Array System Supports Nanophotonics Applications

A research team from the University of New Mexico (UNM) and the Autonomous University of Madrid has applied periodic arrays containing nanoparticles of different sizes — as opposed to more conventional arrays that contain nanoparticles of a singular, uniform size — to generate coherent light of desired colors. Receiving a response from nanophotonic applications, such as ultrasensitive biosensing and nanoscale lasing, is contingent upon a spectrally narrow range of colors, or light wavelengths. Systems featuring periodic arrays can attract the desired spectrally narrow responses. The research team’s application delivered increasingly narrow responses. The responses were additionally more robust to...
