CA 2428913
An optical module according to the invention includes an optical fiber, a planar lens, and a flat plate-like transparent member for optically coupling the optical fiber and the planar lens to each other. The transparent member has a nearly spherical concave portion formed in a surface of the transparent member. An end surface of the optical fiber is inserted into the concave portion of the transparent member so as to abut thereon and bonded and fixed thereinto. Further, a surface of the transparent member opposite to the surface in which the concave portion is formed is joined to a surface of the planar lens to make an optical axis of the optical fiber coincident with an optical axis of the planar lens. The concave portion is filled with a filler material having a refractive index higher than that of the transparent member to thereby fix the optical fiber.
