Title: Optical branching circuit and its production
Inventor: SATOU TOYOSAKU
IPC: G02B6/13
Filed: 1981-09-18
Abstract: PURPOSE:To decrease light losses by formation of a main waveguide and a subwaveguide having a circular shape in section by irradiating the UV light propagated through an optical fiber of graded index type to a photosensitive resin coated on a glass substrate thereby curing the resin. CONSTITUTION:A glass substrate 6 is disposed between an optical fiber 1 and optical fibers 2, 3, and a photosensitive resin is coated thereon. UV light of the wavelength region sensitive to the resin is throttled with a lens and is made incident to the fiber 1. The UV light propagates in the fiber 1, cures the uncured photosensitive resin successively from the end face of the fiber 1 until it arrives at the end face of the fiber 2. The UV light is made incident from the fiber 2 as well to cure the photosensitive resin. The uncured parts are removed by developing, whereby a main waveguide 4 is obtained. In the same manner, the photosensitive resin is coated and the UV light is made incident to the fiber 3. The resin is processed in the same manner, whereby a subwaveguide 5 is obtained. Thus the main waveguide 4 and subwaveguide 5 having a circular shape in section of the diameter approximately equal to that of the fibers are formed. Thus light losses are decreased considerably as compared to conventional  branching circuits of a square or trapezoidal shape.

A non-woven fabric 5 is wound on the outer circumference of the spacer 3. The water reacts with the powder of the calcined gypsum and the calcined gypsum 2 condenses and solidifies when the water infiltrates the optical fiber sensor constituted in such a manner and, therefore, the optical fiber is microbent by receiving irregular external force and is thereby increased in transmission loss. The point where the loss is generated is, therefore, discovered by measuring the backward scattering.
