Abstract:
1. An optical waveguide member comprising: a first cladding section; a second cladding section joined to said first cladding section; and a plurality of core sections formed between said first cladding section and said second cladding section; said first cladding section comprising: a major portion including a first surface, a second surface opposite to and in a different plane than said first surface, a first end face extending in a direction perpendicular to both of said first surface and said second surface, and a plurality of grooves provided respectively on said first surface and said second surface to extend in a direction perpendicular to said first end face; and an auxiliary portion integrally connected to said major portion at a side opposite to said first end face, said auxiliary portion including a reflecting surface extending in a direction obliquely intersecting both of said first surface and said second surface of said major portion, and a second end face extending in a direction obliquely intersecting said reflecting surface and perpendicular to said first end face of said major portion; said plurality of core sections comprising: a first set of core sections formed along said plurality of grooves provided on said first surface of said major portion of said first cladding section; and a second set of core sections formed along said plurality of grooves provided on said second surface of said major portion of said first cladding section; said second cladding section being configured to cover said first set of core sections and said second set of core sections formed respectively on said first surface and said second surface of said major portion of said first cladding section, and to be joined to said first and second surface; wherein light propagating through said first set of core sections formed on said first surface of said major portion of said first cladding section and light propagating through said second set of core sections formed on said second surface of said major portion of said first cladding section are reflected by said reflecting surface and propagate through said auxiliary portion of said first cladding section.
