摘要：

We experimentally investigate the optical loss of graded-index (GI) core polymer optical waveguides with a 45-degree mirror on their one end fabricated using the photo-addressing method. In addition, we also theoretically analyze the loss of GI square-core waveguides with mirrors using a ray-trace simulation tool. Then, in the waveguide based optical link including the optical path conversions via 45-degree mirrors, we show that GI waveguides realize lower total optical loss than conventional step-index (SI) core waveguides. The lower loss in the GI waveguide link is attributed to the tight optical confinement at the core center even after reflection at the mirrors. (C) 2016 Optical Society of America
