| Outline of Final Research Achievements |
Optical wiring is promising to reduce the size and power dissipation of computers. One of the issues of the optical wiring is “easy optical couplings between devices.” In the present work, we proposed a self-aligned optical coupling of the self-organized lightwave network (SOLNET) with the phosphor-targeting effect, and attempted to demonstrate the proof-of concept by simulations and experiments.
It was found that SOLNETs formed by the two-photon photochemistry widen the lateral misalignment tolerance. For a lateral misalignment of 1 um, in optical couplings between optical waveguides with 600-nm-wide cores an optical solder function exhibiting a coupling loss of 0.4~0.6 dB is expected, and in couplings between optical waveguides with 3-um-wide and 600-nm-wide cores a mode-size conversion optical solder function exhibiting a coupling loss of 1.2~1.4 dB is expected.
