<p><P>PROBLEM TO BE SOLVED: To provide an optical switch with which a traveling route of an optical signal as it is without converting the optical signal into an electric signal is switched with a simple structure. <P>SOLUTION: A twisted nematic liquid crystal element 1 is used as an electrooptical means. The first reflection polarizing plate 2 as a polarized light separating means to separate incident light Ri into polarized light components R1, R2 of which the respective planes of polarization mutually perpendicularly intersect and the first reflection mirror 3 as the first optical deflection element are arranged on the side of the liquid crystal element 1, on which the incident light Ri is made incident. The second reflection polarizing plate 4 as a polarized light combining means to combine the polarized light components R1, R2 so as to form outgoing light Ro which is subsequently emitted to a specified direction and the second reflection mirror 5 as the second optical deflection element are arranged on the side of the liquid crystal element 1, from which the outgoing light Ro is emitted. <P>COPYRIGHT: (C)2004,JPO</p> |
