Bridging Between Photonic Scales
Abstract
We show confinement of light traveling in micron-size waveguides into nm-size regions. Most photonic dielectric cavities have been traditionally limited to sizes that are on the order of the wavelength of light. Here we show a decrease in mode volume by several orders of magnitude over previous dielectric microcavities based on wavelength independent dielectric discontinuities. The principle of reduction of effective mode volume, well below the dimensions of the wavelength of light can be applied to nearly every existing microcavity resonator to enhance not only light emission but also non-linear effects. Such a reduction can enable the demonstration of effective mode volumes of nm-size and increase of Purcell factor by orders of magnitude. This technique may enable new experiments in cavity Quantum Electrodynamics, ultra-sensitive single atom detection, and low threshold lasers
