摘要： PROBLEM TO BE SOLVED: To fix a heat shrinkable tube terminal part without using adhesive at all by retaining a projection at the outer periphery of an optical fiber line on which a heat-shrinkable tube is put. SOLUTION: A heat shrinkable tube retaining implement 7 provided integrally with a connecting part 7-1 at its front end is fitted onto the outer periphery of the flat type multiple optical fiber line 1 and the connecting part 7-1 is fixed by welding, for example, YAG welding, to the end of an optical fiber aligning implement 3. The heat shrinkable tube 2 is put on the outer periphery at the end of the flat type multiple optical fiber line 1 including the heat shrinkable tube detaining implement 7 fixed in such a manner and further, the heat shrinkable tube 2 put thereon is heat treated and is thermally shrunk. Then, even if the optical fiber line terminal part causes a temp. change according to a change in load and environmental temp., the deviation in a position of the heat shrinkable tube 2 is completely suppressed and consequently, the crack and peel of the coating film layer cured by UV rays are entirely obviated.

摘要： PROBLEM TO BE SOLVED: To provide a fiber cord/multi-core fiber cord conversion part of an optical fiber easily producible and with good space efficiency. SOLUTION: Since only a thermal curing type silicone resin coating layer 4 and polyamide resin coating layer 5 are removed over a prescribed length at the terminals 1a of optical fibers 1 and the ribbon of the fibers are formed by aligning the parts where the UV-curing type acrylic resin coating layer is exposed, even if the number of the coated fibers increases, just once stage for forming the ribbon is enough. While the removal of the coatings is required to be executed by as much as the number of the coated fibers, but since the thermal curing type silicone resin coating layers are disposed between the UV- curing type acrylic resin coatings 3 and the polyamide resin coating layers 5, if the polyamide resin coating layers 5 are removed by scoring the layers with two sheets of opposite blades, etc., set with, for example, a gap, the thermal curing type silicone resin coating layers are easily removed by rubbing with gauze, etc. The fabrication is thus made easy. The production is, therefore, easier than by the conventional method of coating and reinforcing each fiber.

摘要： PROBLEM TO BE SOLVED: To provide a waveguide type optical module which has a low power consumption and is low in cost.
SOLUTION: The heat of a sheet heater 3 is confined by an optical waveguide 1, a gel-state silicone adhesive 10, and positioning members 4 and 5, so the heat can efficiently be conducted to the optical waveguide 1. Further, the module is of simple constitution such that the optical waveguide 1 is fixed with the gel-state silicone adhesive 10, so there is no influence of external forces of vibration, a shock, etc., and the cost is reducible. Further, there is not stress caused before by a setting shrinkage of an adhesive. Further, no heterogeneous material is used, so stress due to thermal strain of a package exerts no influence on optical characteristics of the optical waveguide 1.

摘要： PROBLEM TO BE SOLVED: To provide an optical module small in size and variable in optical characteristics without being affected by disturbance. SOLUTION: A magnetic field producing means produces a magnetic field to apply an attractive force and a repulsive force to a metal plate 13 on an optical waveguide substrate 1 and tensile or compressive stress to the surface and inside of an optical waveguide, and the optical waveguide substrate 1 is finely deformed to vary the optical characteristics. When the magnetic field producing means comprises a coil 9 and a current adjusting means, the magnetic force can be varied by adjusting the current flowing to the coil 9 and then the optical characteristics can be varied. An optical waveguide substrate with a thin metal film can be formed by vapor-depositing a metal film on a substrate which is made of the same material with the optical waveguide substrate 1 and thinner than the optical waveguide substrate 1. When the optical waveguide substrate 1 is fixed to a storage tray 6 with an elastic adhesive, it becomes easier to finely deform the optical waveguide substrate 1.
