Planar Photonic Crystal Nanocavities with Active Quantum Nanostructures [PDF]
, 2004 Extreme photon localization is applicable to constructing building blocks in photonic systems and quantum information systems. A finding fact that photon localization in small space modifies the radiation process was reported in 1944 by Purcell, and ...
