<P>PROBLEM TO BE SOLVED: To improve the efficiency of using light radiated to a plurality of optical modulation elements. <P>SOLUTION: This optical switching device 1 radiates light source light from a light source 2 to a space optical modulating means 4 having a plurality of chips 9 having a plurality of optical modulation elements 8 made of electrooptical crystal material arranged in a predetermined state, drives and controls the plurality of optical modulation elements 8, and turns on or off the emitted light of the space optical modulating means 4. The space optical modulating means 4 divides, with a PBS6, the light source light into two linear polarized lights whose polarization planes are perpendicular to each other, and radiates the two linear polarized lights to the plurality of chips 9. <P>COPYRIGHT: (C)2010,JPO&INPIT |
