Abstract:
A method for fabricating a dual fiber optical collimator comprising steps ofa) inserting a GRIN lens into a first short holding tube and a dual fiber pigtail into a second short holding tube;b) adjusting a relative position of said dual fiber pigtail to said GRIN lens on an alignment stage to an optimal position achieving a lowest transmission loss;c) sliding said first short holding tube along said GRIN lens toward said dual fiber pigtail without moving said GRIN lens and meanwhile sliding said second short holding tube toward said GRIN lens without moving said dual fiber pigtail until said first and second short holding tubes are in contact;d) permanently fixing said fiber pigtail, said GRIN lens and said first and second short holding tubes together by applying a first heat curing epoxy;e) permanently fixing said fiber pigtail to a glass tube by applying a second heat curing epoxy; andf) permanently fixing said glass tube to a stainless steel holder by applying a third heat curing epoxy.
