Embedded micro-mirrors for compact routing of multimode polymer waveguides

摘要: The limited scalability of high-speed electrical interconnects drives research on optical interconnect technologies. This work is concerned with compact polymer waveguide routing schemes for printed circuit boards (PCB). developed embedded micro-mirrors are an integral part the layer. micro-structures that make up their bodies fabricated directly onto lower cladding by means UV-laser patterning a photosensitive resin. Vertical and 45°-tilted eventually used as in-plane out-of-plane micro-mirrors, respectively. A wet-chemical deposition process to apply reflective metal layer selectively micro-structures. fabrication processes compatible PCB manufacturing equipment. An electro-optical flex board designed basis transceiver module. Therein implemented mechanical fiducial markers adjustment-free alignment connector micro-mirrors. latter will vertically couple light path from laser- or detector-array array. In second part, experimental approach characterize modal power coupling propagating in waveguides investigated. matrix thereby describe relation between input output distribution waveguide. specific mode launch, required control distribution, realized intensity- phase-controlling spatial modulator (SLM). at end facet analyzed based Fourier transformation.
