OPTICAL BUS AND ITS MANUFACTURE, AND SIGNAL PROCESSOR

摘要

PROBLEM TO BE SOLVED: To improve the transmission efficiency of signal light and to prevent a defect in data transmission by interposing a clearance layer which prescribes the interval between adjacent optical transmission lines between the adjacent transmission lines. SOLUTION: A sheet type data bus 30 has structure formed by stacking optical transmission lines 31 and clearance layers 32 alternately. The optical transmission lines 31 propagate signal light. The clearance layers 32 are adjusted in thickness so that the intervals between photodetecting elements receiving signal lights projected from the respective optical transmission lines 31 match each other, and a thermally vulcanized silicone rubber material as an elastic body of approximately 4.48mm in thickness for each layer is used. The optical transmission lines 31 consist of optical transmission layers 33 and clad layers 34 between which the optical transmission layers 33 are sandwiched. Signal light output parts where signal lights are made incident and projected are provided on end surfaces of the optical transmission layers 33. In the optical transmission layers 33, light scattering bodies which scatter signal lights made incident from the signal light output parts are scattered.
