Photo-induced second-order nonlinearity in stoichiometric 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 Şükrü Ekin Kocabaş, “The Effect of Metal Thickness on Si Wire to Plasmonic Slot Waveguide Mode Conversion,” Süleyman Demirel Üniversitesi Fen Bilimleri Enstitüsü Dergisi, published online 2017-12-28. abstract pdf url second harmonic generation, Raman converters. ... Low Loss and Ultra Flat Rectangular Waveguide Harmonic The linearity of the mm-wave components is evaluated through the assessment of the inter-modulation of these components, especially at the second harmonic band. In this paper, a −17-dB harmonic coupler is designed to pick a strong sample at the second harmonic, while suppressing the fundamental signal at the coupled port.
