Abstract
The present disclosure provides optical waveguide coupling devices and associated methods. In one example, an optical waveguide coupling device can comprise a dielectric grating coupler, a first optical waveguide attached to a first surface of the dielectric grating coupler, and a second optical waveguide attached to a second surface of the dielectric grating coupler. The second optical waveguide can be oriented opposed to the first optical waveguide allowing for communication therebetween via the sub-wavelength grating. Additionally, the dielectric grating coupler can comprise a first dielectric material; a sub-wavelength grating attached to the first dielectric material, the sub-wavelength grating having a higher refractive index than the first dielectric material; and a second dielectric material optically coupled to the sub-wavelength grating.
