Abstract
PURPOSE:To prevent scattering loss owing to the grating while handling light in a two-dimensional flat manner by forming the diffraction grating with grooves being put in the thickness direction on the way or on the wall surface of the thick-film optical transmission lines. CONSTITUTION:An irregular spacing diffraction grating 3 is placed between thick film optical transmission lines 1 and 2, and an optical fiber 4 is connected to the thick film optical transmission line 1. Optical fibers 5, 6, 7 are connected to the thick film optical transmission lie 2. Light 9 incident from the optical fiber 4 spreads in the horizontal direction only, propagates in the thick film optical transmission line, and enters the irregular spacing diffraction grating 3, the diffracted rays 10, 11, 12 whereof propagate in the thick film optical transmission line 2 while being respectively condensed and are respectively coupled to the optical fibers 5, 6, 7. The irregular diffraction grating 3 is the one formed by a holography or electron beam exposure method and an ordinary plane diffraction grating has a function serving also as a condensing system. Since the thickness in the transmission direction becomes just several mum, the scattering of light in the thickness direction hardly occurs. Thence, the scattering loss is prevented.
