摘要：

The power density in the vicinity of a tapered fiber is calculated, with the vectorial model of step-index circular waveguides. For the fundamental HE11 mode carrying a power of 1 Watt, we show that; it is possible to obtain theoretical densities in the range of 10(8) W/cm(2) at the fiber surface. The promising use of such intense evanescent fields as "atomic mirrors" is considered, and the feasibility of these guides is investigated.
