ABSTRACT
One-photon self-organized lightwave networks (SOLNETs) are formed by one-photon photochemistry and two-photon SOLNETs by two-photon photochemistry. The features of one-photon SOLNETs and two-photon SOLNETs are compared for couplings between nanoscale waveguides and couplings between microscale and nanoscale waveguides. In the R-SOLNET the tolerance is 710 nm, and the coupling loss is 2.0 and 1.2 dB for one-photon and two-photon SOLNETs, respectively. In the LA-SOLNET the tolerance is widened up to 2050 nm, and the coupling loss is reduced to 0.4 and 0.6 dB for one-photon and two-photon SOLNETs, respectively. It should be noted that for the nano-nano couplings two-photon R-SOLNETs form a coupling waveguide even when 3000 nm misalignment exists. In the TB-SOLNET and P-SOLNET, the lateral misalignment tolerance for 1 dB coupling loss is 810 nm, and the coupling losses at 1000 nm lateral misalignment are 1.4 and 1.2 dB for one-photon and two-photon SOLNETs, respectively.
