3-Dimensionally crossed polymer optical waveguide with GI circular core using the mosquito method

Abstract

This paper represents 3-dimensional crossing structures of multimode polymer optical waveguide with graded-index (GI) circular cores for optical printed circuit boards (OPCBs), which are fabricated using the Mosquito Method. In this waveguide, the cores are aligned with a 250-pm inter-channel pitch containing both horizontally and vertically bent structures, where the last 6 channels are crossing over the first 6 channels to achieve greater wiring density for channel shuffling.
