Abstract: An optical waveguide manufacturing method includes: receiving a master template having a plurality of individual waveguide structures imprinted thereon; coating the master template with a curable master template stamp material; curing the master template stamp material to form a master template stamp; separating the master template stamp from the master template; imprinting the master template stamp onto one or more first substrates having an imprintable coating to form one or more master template copies, each master template copy having a plurality of individual waveguide structure copies imprinted thereon; curing the one or more master template copies; separating the master template stamp from the one or more master template copies; coating one of the one or more master template copies with a curable working stamp material; curing the working stamp material to form a working stamp for manufacturing optical waveguides; and separating the master template copy from the working stamp.
