The United Nations' International Year of Light was launched in the City of Light (Paris, France) on Monday, and National Science Foundation (NSF) Director France Córdova was there to illumi...
We consider light trapping in photonic crystals in the weak material absorption limit. Using a rigorous electromagnetic approach, we show that the upper bound on the angle-integrated absorption enhanc...
We propose a waveguiding mechanism based on the effective gauge potential for photons. The waveguide geometry consists of core and cladding regions with the same underlying dispersion relation,but sub...
