PURPOSE: To provide an optical interconnection device between boards for attaining economization by eliminating the need of an electric connector and mechanical alignment and also realizing ultrahigh speed and ultrahigh density optical connection between boards. CONSTITUTION: When a light beam from the laser array 1-5 of respective boards 1-1-a to 1-1-e is emitted in two directions, right and left, by a polarizing beam splitter 1-6 and passes the adjacent polarizing beam splitter, a part of the light beam is received by a photodetector and the rest is allowed to pass. By repeating such actions, the light beam advances in free space perpendicularly to the board and is connected to the desired photodetector 1-4. |
