    Abstract: A MZI comprises a pair of folded waveguides (21,22) disposed between a pair of couplers (24,25). Each folded waveguide comprises a pair of segments (21A,21B) intersecting at a reflector (21C). The respective reflectors (21C,22C) are different distances from the couplers to provide a major portion of the differential path length between the two arms. In a preferred embodiment, the reflectors are polysilicon mirrors and can be formed by etching through the intersecting waveguides and depositing polysilicon. The result is a compact MZI that can be used as a multiwavelength reference for a laser light source on a common silicon optical bench chip.

    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.
