Abstract:
1. A method of fixing an optical fiber to a fixture part, comprising: providing a heat-resistant optical fiber including a core and a cladding, and a thin film of microporous silica made substantially of silicon, having on an outer surface thereof micro apertures 2 nm or less in diameter, said thin film being formed on an outer peripheral surface of the optical fiber; placing said heat-resistant optical fiber on an exterior surface of the fixture part to be joined thereto; applying a microporous silica solution made substantially of silicon over said heat-resistant optical fiber and said exterior surface to cover both said heat-resistant optical fiber and said fixture part; and drying said microporous silica solution to form a microporous silica layer so that the heat-resistant optical fiber is fixed onto the exterior surface of said fixture part.
