Bottom-up soft-lithographic fabrication of three-dimensional multilayer polymer integrated optical microdevices

Abstract

We develop a method to efficiently fabricate three-dimensional multilayer polymer microchips for integrated optical applications. This method uses soft lithography to mold the core structures on top of the cladding, layers. By repeating the process, a three-dimensional multilayer integrated optical microdevice, which consists of several layers of individual planar optical devices, is fabricated. We demonstrate a dual-layer microring resonator optical filter device where the devices in the different layers show essentially identical transmission responses.
