Abstract

We present a new coupler device consisting of two stacked directional couplers (4 X 4-coupler as doubly stacked directional couplers). Coupling occurs in both, horizontal and vertical direction. The structure was fabricated by UV- patterning of a stack of spin-coated polymethylmethacrylate layers. It serves as a basic element to study the accuracy requirements for 3D waveguide patterning.
