    • PROBLEM TO BE SOLVED: To provide a light beam adder which is compact in a radial direction with respect to a principal optical axis and capable of producing high-intensity light beams without limitation on the wavelengths of light beams emitted from light sources used. SOLUTION: In the light beam adder, while a reflecting mirror M1 having a through-hole M11 formed in the center of a reflecting surface M12 formed on a surface is arranged so that the center axis line of the through-hole M11 coincides with the principal optical axis L and that the reflecting surface M12 inclines with respect to the principal optical axis L, a first light source 1 is provided which emits a first light of which optical axis L1 coincides with the principal optical axis L from a rear side of the reflecting mirror M1 toward the front side, a second light source 2 is provided to a location shifted from the principal optical axis L, which emits a second light including a low-light-intensity region formed in the center and a high-light-intensity region formed on the periphery, the low-light-intensity region and the high-light-intensity region of the second light are irradiated onto the through hole M11 and the reflecting surface M12, respectively, and the second light reflected by the reflecting surface M12 advances with the first light with its optical axis L2 coincident with the principal optical axis L.

    • PURPOSE:To obtain a polarizing separator suitable for integration by forming striped metallic films along the optical path of an optical waveguide which uses birefringent crystal and by selecting the metallic film that has variations of refractivity which vary one birefringence component greatly. CONSTITUTION:A polarizing separator 1 is constituted by providing many fine parallel linear metallic vapor-deposition parts in an optical waveguide 7 on the top surface of a substrate 2 composed of birefringent crystal and by dispersing them in the crystal of the substrate by a heat treatment; and LiNbO3 is used for the substrate 2 and Li is used as the vapor-deposited metal. When incident light 4 having both mixed polarized waves TM and TE arrives at the polarizing separator 1 with an incidence angle theta, functions of an ne reduction type diffraction grating to both the polarized waves TM and TE are obtained, so the polarized wave TE is emitted in nearly the same direction as the incidence direction. The polarized wave TM is however, diffractied in a direction 5 to make a 2theta direction difference between both the polarized waves TE and TM, so that both the polarized waves are separated.
    • 目的:通过沿着使用双折射晶体的光波导的光路形成条状金属膜,并且通过选择具有大大变化一个双折射分量的折射率变化的金属膜,来获得适合于整合的偏振光分束器。 构成:通过在由双折射晶体构成的基板2的上表面上的光波导7中设置许多微小的平行的线状金属蒸镀部,通过热处理将其分散在基板的晶体中, ; 和LiNbO 3用作基板2,并且使用Li作为气相沉积金属。 当具有两个混合极化波TM和TE的入射光4以入射角θ到达偏振光分离器1时,获得了对于偏振波TM和TE两者的还原型衍射光栅的功能,因此发射极化波TE 与入射方向几乎相同的方向。 然而,偏振波TM在方向5上衍射,从而在两个偏振波TE和TM之间产生2θ方向的差异,使得两个偏振波分离。
