<p>An optical device includes, in a predetermined section of an optical fiber (1), a first functional part (7) having a plurality of Faraday crystal columns (5) that are parallel to each other and almost penetrating perpendicularly to an optical axis (2) of an optical fiber (1) through a core thereof, and a second functional part (8) having a plurality of holes (6) that are parallel to each other and almost penetrating perpendicularly to the optical axis (2) of the optical fiber (1) through the core thereof. A longitudinal direction of the Faraday crystal columns (5) and a longitudinal direction of the holes (6) form an angle of 45 degrees along a plane perpendicular to the optical axis (2). Thus, the optical device can be realized only by processing the optical fiber. <??>An aspect of the present invention is directed to a method of fabricating a photonic crystal. The method includes the step of forming the photonic crystal by making, in a predetermined section along an optical axis of an optical fiber composed of a core through which light propagate and a clad surrounding the core, a plurality of columns penetrate through the core. <IMAGE> <IMAGE> <IMAGE></p> |
