Chapter 5 Near-Field Optical Micromanipulation
5.1 INTRODUCTION
The domain of near-field optics is undoubtedly a buoyant and prolific topic in current photonics. This area, which is typically associated with the notion of evanescent waves and novel hybrid structures, has come to the fore due the prospects of overcoming the “diffraction limit of light”—the bottleneck that is created in all forms of optics applications because we cannot focus a light beam down to a spot size of arbitrarily small dimensions, but rather are restricted to approximately half the wavelength of the light in the host medium. The motivation of studying near-field optics is in the realization of a new generation ...
