Circuit a photonic crystal having a matching modes guides and the optical system comprising the said circuit with an optical fiber

摘要

The present invention relates to a circuit with photonic crystal comprising a guide made in a membrane of the photonic crystal to the surface of a substrate and an adapter of the coupled mode to said guide, characterized in that the membrane comprises a central point constituting the adapter of the method with a gradient of a cross section in the termination of the said guide, said rod being suspended so as to allow the propagation modes of a symmetrical manner. It also relates to an optical system incorporating said circuit coupled to an optical fiber.
