The str Efficient surface second-harmonic generation in slot micro It results from the modulation of the waveguide dispersion by slot structure. The slot structure enlarges the waveguide dispersion by more evanescent field propagating outside the fiber, making β 1 of the pump wave in fundamental mode and β 2 of the second-harmonic wave in high-order mode matched at a shorter wavelength.

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.

Abstract We present for the first time second harmonic generation in amorphous stoichiometric Si 3 N 4 waveguides grown via low pressure chemical vapor deposition. An effective second-order susceptibility (χ (2)) is established via the coherent photogalvanic effect.A waveguide was designed to phase match a horizontally (parallel to the waveguide width) polarized hybrid EH 00 mode at 1064 nm Photoinduced χ(2) for second harmonic generation in SPIE Digital Library Proceedings.
