Abstract
PURPOSE: To make possible coupling of the output light of miniature and multiple optical fibers to one optical fiber at low losses by combining a curved face mirror or plural plane mirros and lenses for collimating.
CONSTITUTION: 1 thru 4 are optical fibers for input, 11 thru 14 are focusing type rod lenses for collimating, 30 is a glass substrate, 31 is a parabolic mirror formed at the end face of the glass substrate 30 and 100 is an optical transmission fiber which is placed in the position of the focus of the parabolic mirror 31. The output light of the optical fiber 1 is made to parallel beams by the rod lens 11. The parallel beams then enter the glass substrate 30 and are reflected by the parabolic mirror 31. The light beams reflected by this parabolic mirror 31 are reduced in diameter and are coupled to the optical fiber 100. Since the device is constituted in this way, coupling to the multiple optical fibers is made possible.
