Prospects for giant optical nonlinearity on a chip

TL;DR

This paper explores the potential of using organic dye molecules near optical waveguides on a chip to serve as single-photon sources and to generate significant optical nonlinearities, advancing quantum information processing.

Contribution

It introduces a novel approach of integrating organic dye molecules with photonic chips to achieve giant optical nonlinearities and single-photon sources for quantum computing.

Findings

Organic dye molecules can act as single-photon sources.

Molecules near waveguides can produce large optical nonlinearities.

Potential application in quantum information processing.

Abstract

We point out that individual organic dye molecules, deposited close to optical waveguides on a photonic chip, can act as single photon sources and can also provide localised, giant optical nonlinearities. This new atom-photon interface may be used as a resource for processing quantum information.
