Abstract:
A method for fabrication of components having at least one fiber taper receptacle, comprising the steps of:A) fabricating a microstructure body comprising the steps of:1) coating a substrate with a radiation-sensitive material, said radiation-sensitive material having a thickness which decreases continuously in a first direction across at least a transitional region of said radiation-sensitive material;2) forming a structure, substantially in a shape of a trough which is essentially rectangular in cross section, in said radiation-sensitive substrate coating by a light exposure process, said structure continuously tapering in a second direction across at least a tapering region thereof, said light exposure process conducted so that said tapering region and said transitional region come to overlap;B) electroforming a form tool by utilizing said microstructure body, said form tool having a surface which is a negative of said microstructure body; andC) molding an optical component having at least one fiber taper receptacle by utilizing said form tool as a mold.
