ABSTRACT:
An optical coupler for coupling energy from a laser diode bar is disclosed. The coupler includes multiple rectangular optical fibers that each have a cylindrical lens which is an integral part of each fiber end. The fiber ends are held in a fixed spatial relationship by a retainer. In one coupler embodiment, each fiber end is shaped to define the cylindrical lens. In another coupler embodiment, each fiber end carries a lens shaped from an optical medium. Methods of making the couplers are also disclosed.
