title = "Numerical Phase Matching Optimization of nonlinear Optical Phase Conjugation in Several Multimode Nano-rib Waveguides",
abstract = "Mid-Span Optical Phase Conjugation (OPC) is one method to compensate nonlinear signal degradation in long-distance optical transmission system and it is required a high conversion efficiency over a high wavelength-range. To realize that, we investigated and optimized multi-modal Nano-rib waveguides made of several semiconductor materials and theoretically achieved optimal phase matching and identified solutions with higher idler conversion efficiency. Compared with Nano-rib waveguide with Si as the core material and SiO2 as the substrate: Si core and Si3N4 substrate increase efficiency by 0.85\% with 1600nm rib width and 60nm slab height; Al0.5Ga0.5As core and Si3N4 substrate increase efficiency by 10.48\% with 1600nm rib width and 70nm slab height; LiNbO3 core and Si3N4 substrate increase efficiency by 11.33\% with 5000nm rib width and 130nm slab height. All the above optimal results were obtained when the optical signal, pump1, pump2, and idler were in the TE2 mode.",
