| 1. A lens-incorporating optical waveguide comprising:
a core that includes a first portion having a light propagating end-face;
a clad enclosing the core; and
a collimating lens disposed in the first portion of the core, the lens being separated from the end-face by a core material
so as to cross a propagating direction of light, wherein
the core is substantially uniform except for including the lens,
the lens-incorporating optical waveguide is a muitimode optical waveguide, and
the clad encloses the lens within the core.
