Low loss multimode polymer shuffling optical waveguide for high-density optical circuit

Abstract

To realize free optical wiring patterns on printed circuit boards (PCBs), polymer shuffling optical waveguides are fabricated, in which both crossing and curved core structures are combined. The obtained GI polymer shuffling waveguides show low insertion loss independent of the crossing angle and core size. The GI-core polymer shuffling waveguide is a key device for low loss and high density on-board optical wiring.
