Abstract:
An optical fiber/optical component assembly, comprising:at least one light-emitting optical component; at least one light-transmitting optical fiber having a longitudinal axis; and at least one optical coupler between said at least one light-emitting optical component and said at least one light-transmitting optical fiber for optically matching said at least one light-emitting optical component with said at least one light-transmitting optical fiber; said at least one optical coupler comprising: a plate-like lens element having a front end face and a rear end face with a circular lens on said rear end face, said circular lens having an optical axis coaxial with said longitudinal axis of said at least one light-transmitting optical fiber and having an aperture, said front end face and said rear end face being strictly parallel to each other and are machined to a high degree of flatness; a fiber termination holder for holding one end of said light-transmitting optical fiber with a through central opening into which said one end of said light-transmitting optical fiber is moveably inserted with a tight fit, said through opening having a diameter equal to a diameter of said circular lens; a spacer for distancing said light-emitting optical component from said plate-like lens element for a distance at which said aperture of said circular lens correspond substantially to the entire cross section of a light beam emitted from said light-emitting optical component; and a fiber locking element with means for the fixation of said light-transmitting optical fiber to said fiber termination holder in a position, in which said light-emitting optical component is optically matched to said light-transmitting optical fiber for transmitting maximum light energy.
