For future optical transmission systems with high data transmission rates and capacity, we have proposed nanometer-scale photonic devices (i.e., nanophotonics devices). These devices consist of nanometer-scale dots, and an optical near-field is used as the signal carrier.
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...
