Laser diode to fiber reflective coupling.

摘要

A mechanism for coupling radiation from a laser diode (3) into an optical fiber (5) utilizing a spherical mirror (20) is disclosed. To compensate for the disparity in numerical apertures between the laser (3) and fiber (5), the laser emission facet (10) is located closer to the spherical mirror (20) than the one to one imaging plane and the fiber entrance face (6) is located further from the mirror (20) than the one to one imaging plane.
