摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid drive type optical switch which has no leakage of a refractive index matching liquid from a groove for optical path switching. SOLUTION: Alloy 15, having higher heat-resisting temperature than the resin used as a sealing member for the refractive index matching liquid 14, is adopted, and resistance to higher temperature (150 deg.C) can be obtained and the refractive index matching liquid 14 will not leak from the groove 5 for optical path switching, so that the liquid crystal drive type optical switch has high reliability.

摘要： PROBLEM TO BE SOLVED: To provide a liquid drive type optical switch which is free of variance in the amount of refractive index matching liquid in a groove for optical path switching. SOLUTION: A space 12, which swells in a bump shape, is formed halfway in an injection groove 11. Hence, when resin 13 for sealing is injected from the outside, after a fixed amount of refractive index matching liquid has been injected into the groove 5 for optical path switching, the resin 13 enters to up to the bump-shaped space 12 to seal it, so that the amount of the refractive index matching liquid is prevented from varying.

摘要： PROBLEM TO BE SOLVED: To provide a liquid drive type optical switch which has, no variation in loss. SOLUTION: The wall surface of a groove 5 for optical path switching is coated with a substance 19 having surface tension which is smaller that of than refractive index matching liquid 13. Hence the refractive index matching liquid 13 does not form a thin film on the wall surface of the groove 5 for optical path switching, even if the wall surface is made oil-repellant and air is present in an area 17b for shielding cores 2a and 3a in the groove 5 for optical path switching so that the loss of the optical path will no longer vary.
