摘要： The present invention is directed to an optical waveguide module which is arranged to be free from a breakage of a coupling part of an optical waveguide and optical fibers which are housed in a housing and deviation of an optical axis at this coupling part even though a tensile force is applied to optical fibers. A waveguide board having an optical waveguide is housed in a housing and an optical connector to which bare optical fibers are connected is bonded to an end face of the waveguide board to form a first holding part. An optical fiber conductor and an optical fiber tape are introduced into the housing through a side wall of the housing, and the covering parts of the optical fiber conductor and an optical fiber tape are bonded to the side wall of the housing with a bonding agent to form a second holding part. The bonding strength of the second holding part is determined to be larger than the bonding strength of the first holding part.

Each plate-like birefringent substance receives and transmits incident light, and has a corresponding optical axis which is inclined with respect to a direction of the incident light. The optical isolator also has first and second magneto-optical materials, each for rotating a plane of polarization of the incident light. The optical axis of the second plate-like birefringent substance is rotated by one of -45.degree. and 135.degree. about a first axis which is perpendicular to a surface of the first plate-like birefringent substance. The optical axis of the third plate-like birefringent substance is rotated by one of 45.degree. and 225.degree. about a second axis which is perpendicular to the surface of the first plate-like birefringent substance. The optical axis of the fourth plate-like birefringent substance is rotated by one of -90.degree. and 90.degree. about a third axis which is perpendicular to the surface of the first plate-like birefringent substance. The first and third plate-like birefringent substance have equal thicknesses. The second and fourth plate-like birefringent substances are (1+.sqroot.2) times as thick as the first plate-like birefringent substance. The first and second magneto-optical materials rotate the plane of polarization in opposite directions. Finally, the optical isolator has an element for magnetizing the first and second magneto-optical materials.
