The principle of operation of fiber-to-planar-waveguide grating couplers has been established experimentally and theoretically. Initial experiments yielded coupling fractions up to 6 and showed the expected angular behavior. Further development of fiber-planar waveguide grating couplers should allow the coupling of single-mode fibers to single-mode planar guides with efficiencies that approach 90. Multimode fibers may also be coupled but with reduced efficiencies which depend on the acceptable angular spread of the coupled beams. Author
