OPTICAL INTERCONNECTION SYSTEM AND OPTICAL INTERCONNECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a system and technique of high energy efficiency in which interconnections are sustained even after the irradiation with control light is ceased after the connection pattern thereof is established.;SOLUTION: The system is provided with a first signal light input section 5 which has first and second photorefractive crystals 7 and 8 arranged apart spacing from each other, a beam splitter 9 arranged between the two photorefractive crystals 7 and 8, and a plurality of channels ch 1 to ch 4 inputs the first signal light from the respective channels to the first photorefractive crystal 7 and the second signal light input section 6 inputs the second signal light from the respective channels to the second photorefractive crystal 8, a second signal light input section 6 which has a plurality of channels ch 5 to ch 8 and input the second signal light from the respective channels to the second photorefractive crystal 8, and a control light input section 13 which inputs the control light 10 having the intensity distribution for determining the channel connecting pair of the first signal input section 5 and the second signal input section 6 from a diagonal direction toward the beam splitter 9.;COPYRIGHT: (C)2005,JPO&NCIPI
