Abstract

PURPOSE:To simplify the constitution and to reduce a loss of propagation by combining a wedge-shaped prism, having a reflective film 14c, with a polarizing- separating element. CONSTITUTION:Optical trunk fibers 11a and 11b of a data bus are arranged opposing to each other with interposing lenses 12 and 13 of a refractive-index distribution type. Lenses 12 and 13, having the distribution that light is reduced from the centers to the outer circumference at right angles to the center axes in proportion to the square of radiuses, zigzag light. Setting the length of each lens a quarter the zigzag pitch leads light from a spot light source, placed on the flank, as a parallel beam. Therefore, light beams from fibers 11a and 11b become nearly parallel between lenses 12 and 13. So that part of light in the optical path between lenses 12 and 13 will be occluded, wedge-shaped prism 14 having reflective film 14c is interposed, and then part of light in fiber 11 is led out to polarizing prism 15, where it is separated into beam in mutually orthogonal polarization directions.
