Optical coupling device with anisotropic light-guiding member

摘要

An optical coupling device in which there is interposed between optical elements, such as single-mode optical fibers or laser diodes, an anisotropic light guiding member formed by a periodic two- or three-dimensional arrangement of two or more kinds of dielectric materials of different dielectric constants to develop a photonic band-gap to inhibit the propagation of light in all directions except a particular one.
