OPTICAL SWITCH AND MAGNETOOPTICAL CIRCUIT USING SAME, AND METHOD FOR MANUFACTURING MAGNETOOPTICAL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an optical switch whose switching speed is fast and which has superior durability, a magnetooptical circuit, and a method for manufacturing the magnetooptical circuit.;SOLUTION: This optical switch includes an optical transmission path (2) made of a dielectric, a magnetic body (3), and a magnetic field application part (4) which changes the magnetized state of the magnetic body (3) by applying a magnetic field to the magnetic body (3), which is arranged nearby the optical transmission path (2) so that light traveling through the optical transmission path (2) is reflected by a surface of the magnetic body (3).;COPYRIGHT: (C)2005,JPO&NCIPI
