Benefiting from the above mentioned advantages, second harmonic generation (SHG) in nonlinear waveguide structure can be realized under lower light powers, providing higher SH efficiency and more choice of different modes than the bulks 19. Second-harmonic generation in silicon waveguides strained ... Silicon photonics meets the electronics requirement of increased speed and bandwidth with on-chip optical networks. All-optical data management requires nonlinear silicon photonics. OSA | Efficient second harmonic generation in internal ... We theoretically propose an internal asymmetric plasmonic slot waveguide (IAPSW), containing two different materials in the slot region. The IAPSW is used for second harmonic generation (SHG) at a wavelength of 1.55 μm. The required phase matching condition is satisfied between the 0th-order mode at the fundamental frequency and the 1st-order mode at the second harmonic frequency. Highly efficient phase-matched second harmonic generation ... harmonic generation (SHG) efficiency in silicon compatible waveguides by considering an asymmetrical plasmonic slot waveguide geometry and a χ (2) nonlinear polymer infiltrating the slot.
Second-order nonlinear waveguides based on strained silicon can achieve phase matching by dispersion-engineering. [74] So far, however, experimental demonstrations are based only on designs which are not phase matched. [75] It has been …

Nevertheless, second-harmonic generation (SHG) with peak power-conversion efficiency as high as ~3% has been reported to occur in optical fibers in 1986 [1]. Initially, this phenomenon could not be reasonably explained by core-cladding interface or bulk multipole moment contributions to the secondorder nonlinearity [2].
