摘要： PROBLEM TO BE SOLVED: To facilitate formation of a self-forming optical waveguide having small transmission loss, without having to use a solvent. SOLUTION: As in Fig. (a), a first setting resin liquid 1 is filled in an acrylic transparent container 3 having a shape of a rectangular parallelepiped with an opening on top and then, a plastic optical fiber 4 is immersed therein, with the first setting resin liquid 1 irradiated with a laser beam through the plastic optical fiber 4. The first setting resin liquid 1 is gradually hardened through the laser beam irradiation, with an axial core 5 formed by self convergence (b). The unhardened first setting resin liquid 1 is removed from the opening of the transparent container 3. At this time, as in (c) the unhardened first setting resin liquid 11 sticks to the surface of the core 5 and the inner face of the transparent container 3 and remains therein. Then, a second setting resin liquid 2 is filled in the transparent container 3. At this time, the unhardened first setting resin liquid 11 is dispersed in the second setting resin liquid 2. Thereafter, the second setting resin liquid 2 is photoset using ultraviolet rays to form a clad (d). COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To accurately measure an alcohol concentration in a breath by correcting influence of a vapor concentration.SOLUTION: Light emitted from a light source 10 is divided by a polarization beam splitter 13 into p-polarized light transmitted and s-polarized light reflected. The p-polarized light is reflected by an optical sensor element 11 and then reflected by the polarization beam splitter 13 so as to be output to a photodetector 15 as output light 1. The s-polarized light is reflected by an optical sensor element 12 through a quarter wave plate 14, passes through the quarter wave plate 14 again and passes through the polarization beam splitter 13 so as to be output to the photodetector 15 as output light 2. The optical sensor element 11 responds to an alcohol concentration and a vapor concentration to change its reflectance, and the optical sensor element 12 responds to a vapor concentration to change its reflectance. The intensity of the output light 1 is increased as the reflectance of the optical sensor element 11 is lowered, and the intensity of the output light 2 is reduced as the reflectance of the optical sensor element 12 is lowered.
