高速.高度光インターコネクションのための屈折率分布型ポリマー並列光導波路

摘要

We demonstrate the high performance of multi-channel graded-index type polymer paralleloptical waveguide for high-speed and high-density optical interconnection. In the cores of GI typewaveguides, the output optical field of the propagating modes is confined near the core centerindependent of the outer core shape, and thus, low propagation loss and low inter-channelcrosstalk can be achieved. Due to the low inter-channel crosstalk property, we verified that a verysmall pitch-size (high-density) alignment was also realized in the GI polymer parallel opticalwaveguides.
