We demonstrate a novel method for concentrating optical energy to a nanometric region using energy transfers among CuCl quantum dots in a NaCl matrix. The optical energy was concentrated to 10 nm in diameter
Summary form only given. Recently, atom manipulation by using optical near fields has been attracting a lot of interests. Optical near field can be localized in a nanometric region, being free from the diffraction limit in contrast to propagation light. The intensity distribution of optical near field decays rapidly as an exponential-like function. Because such a spatially inhomogeneous light field...
