Optical fiber structure, optical communication apparatus and manufacturing process for manufacturing the same

An optical communication apparatus comprising:

• an optical fiber structure comprising:
• a core portion;
• and
• a cladding portion enclosing the core portion, wherein the cladding portion includes a light reflection surface and a substantially flat light incident surface, the light reflection surface is inclined at an angle of about 30 degrees to about 60 degrees with respect to the core portion;
• and
• a light source positioned below the light incident surface and configured to emit a light beam into the optical fiber structure through the light incident surface to the core portion of the optical fiber structure.
