Claim Text:
1. A method for manufacturing a metallic stamp for manufacturing a polymer optical device, the method comprising: a) engraving a unit device planar lightwave circuit (PLC) mold pattern on a first silicon substrate through electron beam lithography and an etching process; b) embossing a unit PLC device pattern on a first poly methyl methacrylate (PMMA) sheet using the PLC mold pattern by a thermal imprint process; c) performing an annealing to the unit PLC device pattern imprinted on the first PMMA sheet; d) forming a first groove pattern, which is an embossed pattern, for supporting an optical fiber, using a second poly methyl methacrylate (PMMA) sheet; e) aligning the first groove pattern and the unit device pattern; f) making an integrated polydimethylsiloxane (PDMS) mold for a unit device using the aligned unit PLC device pattern and first groove pattern, the integrated PDMS mold having an engraved pattern which corresponds to the aligned unit PLC device pattern and first groove pattern; and g) producing a plurality of integrated PDMS molds by repeating the steps of a) through g); h) forming a PDMS pattern using the plurality of integrated PDMS molds, the PDMS pattern having a pattern corresponding to the plurality of integrated PDMS molds; and i) making the metallic stamp through electroforming using the PDMS pattern, wherein the step of forming the PDMS pattern comprises:
