Beschreibung
Zusammenfassung:The invention relates to a photonic crystal circuit comprising a guide produced in a photonic crystal membrane on the surface of a substrate and a mode adapter coupled to said guide, wherein the membrane includes a central point constituting the mode adapter having a section gradient as termination of said guide, said point being suspended so as to allow the propagation of modes in a symmetrical manner. It also relates to an optical system incorporating said circuit coupled to an optical fiber.
