A fiber optic collimator system, a fiber optic collimator array, and a fiber optic collimator array system, which can reduce difficulty in an alignment process, minimize a coupling loss, and prevent the optical characteristics from deteriorating. An optical fiber is fused to one end of a GRIN lens made of quartz glass containing one or more selected from Sb2O3, Ta2O5, TiO2 and ZrO2 as a refractive index regulating substance, to form an optical fiber with a GRIN lens.
