A monolithic optical coupling module for coupling a light beam is disclosed. The optical coupling module has a light beam input portion, a light beam output portion and at least one integrally formed light beam attenuator between the light beam input portion and the light beam output portion. The monolithic optical coupling module may be unitarily fabricated of a moldable polymeric material. The light beam attenuator may be a roughened surface or a roughened internal portion. A method for forming the monolithic optical coupling module is also disclosed.
