A New Method of Optical Interconnection for Multi-stacked Planar Optical Circuit Boards using 45° Reflection Coupling

초록

We developed, for the first time to our knowledge, a new method of providing optical interconnection between multi-stacked planar optical waveguide boards using 45° reflection coupling. This consists of two 45° reflection mirrors vertically stacked and facing each other. We developed special molds that can imprint rectangular polymer waveguides and 45° reflection mirrors at the same time, using ultraviolet imprinting technique. This opens up new ways of optically integrating multiple stacks of optical wire boards for high-density photonic circuit integration.
