UV-nanoimprinting lithography of Bragg Gratings on hybrid sol-gel based channel waveguides
Abstract(#br)We report on the fabrication in a single step of a channel grating loaded waveguide on Titanium based hybrid sol-gel material.(#br)This result has been accomplished by the merging of several lithographic techniques, namely conventional, laser interference, and soft lithography.(#br)Conventional lithographic processes have been employed for fabricating channel waveguides on a previously holographically written planar photopolymerizable sol-gel film.
