Waveguide Multimode Directional Coupler for Harvesting ry waveguide, the signal at the fundamental frequency propagates as the dominant TE10 mode. The power in the 2nd harmonic sig-nal propagates as higher order modes [4]. If an aperture is cut in the shape of a narrow rectangular slot parallel to the y-axis along the primary waveguide narrow wall, the coupling to the TE10 Photoinduced χ(2) for second harmonic generation in 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

We theoretically analyse quasi-phase matched second harmonic generation in a quadratic slot waveguide. Our results show that in this system both fundamental frequency and second harmonic (SH) modes can be confined in a nano-sized low-index region with the mode overlap integral intensity two orders larger than that achieved in the form birefringence phase matching slot waveguide and the ...

The maximum measured second-harmonic conversion efficiency amounts to 0.4% in a waveguide with 0.9 x 1 {\mu}m$^2$ cross section and 36 mm length, corresponding to 53 {\mu}W at 532 nm with 13 mW of IR input coupled into the waveguide. The according $\chi^{(2)}$ amounts to 3.7 pm/V, as retrieved from the measured conversion efficiency. kocabas.gitlab.io - Webpage of Şükrü Ekin Kocabaş
Internal Asymmetric Plasmonic Slot Waveguide for Third We propose an internal asymmetric plasmonic slot waveguide (IAPSW) containing two different materials in the slot region for third harmonic generation (THG) from 2.25 μm. In the IAPSW, the required phase matching condition is satisfied between the 0th-order mode at the fundamental frequency and 1st-order mode at the third harmonic frequency.
