Abstract

PURPOSE:To make a light circuit small and lightweight by disposing a plurality of the optical fibers to be photocoupled in the V-groove of a support base provided with the V-groove and a hole in the position corresponding to the point of coupling of the optical fibers and positioning them, then securing these in the corresponding part of the hole, putting a sleeve on the other end of each optical fiber and fixing these into the V-groove into one piece. CONSTITUTION:For example, an incident optical fiber 5 having no resin covering, an optical fiber 6 having a cut face of 45 deg. and provided with an optical film having branching or wave branching characteristics and a branching fiber 7 are disposed in the V-groove 2 of a support base 1 of stainless steel or the like, and after these are positioned an adhesive agent having a refractive index same as or approximate to that of the optical fiber cores is flowed in the position of the hole 3 provided in the coupling part of the support base 1, whereby they are joined and secured. Re inforcing sleeves 8 made of stainless steel or the like are covered on the other ends of the respective optical fibers 5-7 and these parts are fixed into the sleeve groove 4 by means of an adhesive agent into one piece. Thereby, the light circuit can be made small and lightweight.
