Grooved substrates for multifiber optical connectors and for alignment of multiple optical fibers and method for production thereof

摘要

A grooved substrate which has a groove for aligning or positioning an optical fiber therein and which can be advantageously used in a multifiber optical connector or for aligning a multiple optical fiber is formed of an amorphous alloy possessing at least a glass transition region, preferably a glass transition region of not less than 30 K in temperature width. Particularly, the amorphous alloy of M<1>-M<2 >system or M<1>-M<2>-La system (M<1>: Zr and/or Hf, M<2>: Ni, Cu, Fe, Co, Mn, Nb, Ti, V, Cr, Zn, Al, and/or Ga, La: rare earth element) possesses a wide range of DeltaTx and thus can be advantageously used as a material for the grooved substrate. Such a grooved substrate can be manufactured with high mass-productivity by a metal mold casting method or molding method.
