Highly efficient channeling of single photons into guided modes of optical nanocapillary fibers

Abstract

We report numerically the efficient channeling of single photons from a single quantum emitter into guided modes of optical nanocapillary fibers (NCFs). The NCF is formed of a liquid core optical nanofiber with inner and outer diameters. We optimize the inner and outer diameters of the NCF filled with water medium by placing a single dipole source (SDS) inside. The maximum channeling efficiency of 52% is found when the radially polarized SDS is placed at the center of the NCF filled with the water medium. The optimum inner and outer diameters of the NCF are 100 nm and 360 nm for the emission wavelength of 620 nm, respectively. Additionally, we investigate the SDS position dependence inside the NCF considering experimental ambiguity in placing a single quantum emitter inside the NCF. We found that the channeling efficiency remains almost constant for the water medium at the optimum condition. The present platform may open a novel route for generating single photons in quantum technologies and detecting single cells in bio-sensing.
