<p><P>PROBLEM TO BE SOLVED: To provide a matrix type optical switch in which a loss of light propagating on an optical path is suppressed, and method of manufacturing the matrix type optical switch. <P>SOLUTION: The matrix type optical switch includes N×M movable mirrors R<SB>1, 1</SB>-R<SB>N, M</SB>disposed at crossings of optical paths (grooves) 2 rrayed in a grid shape and graded-index optical fibers Fr<SB>1, 1</SB>-Fr<SB>N-1, M</SB>, Fc<SB>1, 1</SB>-Fc<SB>N, M-1</SB>inserted between adjacent mirrors R<SB>1, 1</SB>-R<SB>N, M</SB>, wherein the optical paths 2 are switched by putting the movable mirrors R<SB>1, 1</SB>-R<SB>N, M</SB>into and out of the crossings of the optical paths 2, and refractive index of the graded-index optical fibers Fr<SB>1, 1</SB>-Fr<SB>N-1, M</SB>, Fc<SB>1, 1</SB>-Fc<SB>N, M-1</SB>are decreased diametrically from their center axis. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
