Abstract
Various embodiments of the present invention are directed to optical fiber coupling systems and to methods for fabricating optical fiber coupling systems. In one aspect, an optical fiber coupling system includes a first resonant cavity abutting the end of an optical fiber. The optical fiber coupling system includes a second resonant cavity located adjacent to the first cavity. The first and second resonant cavities are separated by a sub-wavelength grating layer configured with a non-periodic sub-wavelength grating. The optical fiber coupling system selectively couples light into and/or out of the optical fiber core.
