Claim 8:
9. An optical ferrule assembly comprising:
an optical ferrule comprising a light input surface, a light redirecting surface, a light output surface, a glass portion comprising glass and the light input surface, and a polymeric portion comprising a polymer and disposed between the glass portion and the light redirecting surface; and
a plurality of optical fibers, each optical fiber comprising a fiber end laser welded to the light input surface, such that a central light ray emitted by the optical fiber enters the optical ferrule through the light input surface and exits the optical ferrule though the light output surface after being redirected by the light redirecting surface, wherein while propagating from the light input surface to the light output surface, the light propagates through the glass and polymeric portions of the optical ferrule.
