Collimator optical fiber integrated embedded in a lens and method of manufacture corresponding

The invention an integrated optical fiber collimator comprising an optical fiber and a graded index collimator lens having a melting temperature lower than that of said optical fiber, and its manufacturing method. According to the invention, one end of said optical fiber penetrates said lens along the optical axis of said lens over a predetermined depth adjusted so that a light beam output from said collimator is substantially collimated.
