【 摘 要 】

The self-organized lightwave network (SOLNET) provides optical solder, which enables self-aligned optical couplings between misaligned optical devices with different core sizes. We propose a low-cost SOLNET formation method, in which write beams are generated within optical devices by excitation lights from outside. Simulations based on the finite-difference time-domain method reveal that the two photon processes enhance optical-solder capabilities. In couplings between 600-nm-wide waveguides opposed with 32-mu m distance a wide lateral misalignment tolerance of similar to 2 mu m to maintain <1 dB loss at 650 nm in wavelength is obtained. The coupling loss at Him lateral misalignment is 0.4 dB. In couplings between 3-mu m-wide and 600-nm-wide waveguides, losses at 650 nm are 0.1 dB for no misalignments and 0.9 dB for 1-mu m misalignment. These results suggest that SOLNETs provide optical solder with mode size converting functions. (C) 2016 The Authors. Published by Elsevier B.V.
