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.
Claims20
An optical fiber coupling system comprising:
- a first resonant cavity abutting the end of an optical fiber including a core;
- and
- a second resonant cavity located adjacent to the first cavity, the first and second resonant cavities separated by a sub-wavelength grating layer configured with a non-periodic sub-wavelength grating, wherein the optical fiber coupling system selectively couples light into and/or out of the optical fiber core.
A method for fabricating an optical fiber coupling system for coupling light into and/or out of an optical fiber, the method comprising:
- depositing a first reflective layer on a substrate;
- depositing a first spacer layer on the first reflective layer;
- forming a sub-wavelength grating layer on the first spacer layer;
- depositing a second spacer layer on a grating layer;
- and
- depositing a second reflective layer on the second spacer layer, wherein the first and second spacer layers have lower refractive indices than the first and second reflective layers and the grating layer.
