Grating couplers are simply components of a photonic circuit that use diffraction to couple light into or out of a waveguide. By utilizing geometry and diffraction, fiber optic cables can be coupled to silicon chips at any location on the chip, instead of just the edges. How does it. An optical fiber grating is a small segment within an optical fiber altered to act as a selective filter for light. This treated area functions like a specialized mirror, reflecting a specific wavelength of light while allowing all other wavelengths to pass through. How does it work? Key to. coupling efficiency is substantially increased by adding a gold bottom mirror to the structures. The measured coupling effi cloButene (BCB) wafer bonding, gold mirror, grating couplers, in en the fiber and the waveguides on a chip causes high insertion losses and high packaging costs.
