ABSTRACT:
An optical coupling structure useful in optical switching devices is described. The optical coupling structure includes a core layer for guiding a light beam exiting a core layer of an optical fiber into a slab waveguide layer. The core layer of the optical coupling structure avoids a power loss of a light beam and establishes an adiabatic coupling. The core layer of the optical coupling structure may have a tapered surface.
