    Abstract: In an optical fiber light source a section of multimode fiber (51) is interposed between an energizing laser (e.g., a diode laser (49)) and a single mode fiber active medium (43). In a preferred embodiment the single mode fiber active medium is surrounded by a multimode cladding (45) coupled to the multimode fiber. The source may serve as a pump laser for a fiber amplifier (30) or as an amplified spontaneous emission source. Arrangements for coupling several energizing lasers to the active medium are also described.

    Abstract: In accordance with the invention, arrays optical sources (20A,20B,20C) are combined in a multilevel planar optical waveguide structure for insertion into an optical fiber laser (21). The basic element of the combiner is a planar array of multiple waveguides (12A,12C) which converge and are gradually tapered to a single output waveguide (14A,14C). A plurality of such elements integrally formed on successive cladding layers provides a high power stack of vertically aligned outputs. An arrangement is described for using such apparatus in the amplification of optical communications signals.
