Abstract
A new directional coupler device using a three-dimensional structure i s presented. It consists of two stacked directional couplers (4 x 4-co upler as doubly stacked directional couplers). Coupling occurs both in horizontal and vertical direction. The device is intended to be the f irst of several devices employing three-dimensional structures. The pr esented device was fabricated by UV-patterning of a stack of spin-coat ed polymethylmethacrylate (PMMA) layers.
