Claim:
1. An optical waveguide assembly, comprising: a waveguide tube member including an input portion, a central portion, and an output portion; and a plurality of closely packed optical waveguides situated in the waveguide tube member, the closely packed optical waveguides having respective input portions with selected polygonal cross-sections; wherein the cross-section of the waveguide tube member central portion and the polygonal cross-sections of the optical waveguide input portions in the waveguide tube member central portion taper along the length of the waveguide tube member central portion such that a cross-sectional area of the waveguide tube member output portion is less than about half the cross-sectional area of the waveguide tube member input portion; wherein the polygonal cross-sections of the closely packed optical waveguide input portions are situated in the waveguide tube member input portion so that each optical waveguide input portion in the waveguide tube member input portion is in contact with but not fused to adjacent optical waveguide input portions.
