Design and Fabrication of Mode Size Adapter using Hybrid Imprint Lithography

초록

Mode size adapters that are needed to interconnect two planar waveguides of different sizes have been designed and fabricated by the imprinting lithography. Optimum dimensions of the adapters were determined by simulation. Molds for the imprint were prepared by noble hybrid imprint lithography which employed both imprinting and photolithography and fabrication of mode size adapters with smooth and sloped taper region was successfully demonstrated.
