Integrated optic waveguide with side gaps of increasing depth to match the waveguide's mode to that of a fibre

摘要: The present invention relates to a waveguide taper. taper has first end (890) and second (892) for being coupled with fiber. core (808) an overall width that progressively increases from the toward fiber such of corresponds diameter Side-gaps (804) are disposed in sides extend into but not across entire core. depth side-gaps In one embodiment, may be aperiodically and/or randomly along length can at different angles direction light propagation
