Multimode polymer optical waveguides with graded index perfect circular cores are fabricated using the Mosquito method. We both theoretically and experimentally confirm that monomer-flow caused by the monomer dispense with needle scan influences the core shape. In addition, we fabricate a waveguide with perfect circular cores showing 1.73-dB lower insertion loss compared to the waveguide with the...
We fabricate a 12-ch. 2-layer graded-index circular core multimode polymer parallel optical waveguide using the Mosquito method, and demonstrate a high core-position accuracy for high density on-board interconnection.
We propose to introduce a densely aligned 2times4 channel polymer parallel optical waveguide with graded-index circular cores for board-level optical interconnection, which is fabricated using the preform method. It is verified that this novel waveguide has sufficiently low loss (0.028 dB/cm at 850 nm and 0.061 dB/cm at 980 nm) and high bandwidth, due to the specific characteristic of the graded-index...
