In some implementations, a fiber optic combiner may comprise an enclosing tube having a geometric shape and multiple optical fibers bundled within the enclosing tube. In some implementations, the multiple fibers comprise at least one optical fiber having a core and a non-circular cladding surrounding the core. The non-circular cladding may cause the multiple optical fibers to have a larger tube fill factor and a lower expected beam parameter product increase factor relative to the multiple optical fibers all having circular claddings.

A light system having a light supply arrangement, a Homogenizing Light Pipe (HLP) and a fiber bundle is disclosed. The light supply arrangement includes a light source and is arranged to supply light to an input end of the HLP. The HLP is configured for scrambling the received light and for delivering a beam of light to a common packed input end of the fiber bundle.
