Abstract
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.sup.1 --M.sup.2 system or M.sup.1 --M.sup.2 --La system (M.sup.1 : Zr and/or Hf, M.sup.2 : Ni, Cu, Fe, Co, Mn, Nb, Ti, V, Cr, Zn, Al, and/or Ga, La: rare earth element) possesses a wide range of .DELTA.Tx 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.
