Abstract

The further miniaturization of integrated optical devices requires investigating optical elements with dimensions on the nano-scale. Methods are therefore needed for detecting and guiding light on a scale much smaller than the wavelength of the light. It is clear that to investigate light-nanostructure interaction in a spatial extension much less than the optical wavelength, one can not in general have confidence in the macroscopic electrodynamics so far popular in near-field optics and photonic band-structures. Instead a microscopic approach treating rigorously the local-field electrodynamics is highly desirable. In this work we present a microscopic theory of near-field optical effect in nanostructured systems. Our theory is based on the rigorous Lagrangian and Hamiltonian formulation of local-field electrodynamics, where the nanostructure optical response is treated quantum mechanically, while the electromagnetic field can be treated either classically or quantum electrodynamically within a unified space-time picture.
