| 3 | Broadband supercontinuum generation in nitrogen-rich silicon nitride waveguides using a 300 mm industrial platform显示文摘We report supercontinuum generation in nitrogen-rich(N-rich)silicon nitride waveguides fabricated through back-end complementary-metal-oxide-semiconductor(CMOS)-compatible processes on a 300 mm platform.By pumping in the anomalous dispersion regime at a wavelength of 1200 nm,two-octave spanning spectra covering the visible and near-infrared ranges,including the O band,were obtained.Numerical calculations showed that the nonlinear index of N-rich silicon nitride is within the same order of magnitude as that of stoichiometric silicon nitride,despite the lower silicon content.N-rich silicon nitride then appears to be a promising candidate for nonlinear devices compatible with back-end CMOS processes. | CHRISTIAN LAFFORGUE SYLVAIN GUERBER JOAN MANEL RAMIREZ GUILLAUME MARCAUD CARLOS ALONSO-RAMOS XAVIER LE ROUX DELPHINE MARRIS-MORINI ERIC CASSAN CHARLES BAUDOT FRéDéRIC BOEUF SéBASTIEN CREMER STéPHANE MONFRAY LAURENT VIVIEN | 2020 | Photonics Research2020，8，3： | 0 |
| 4 | Third-order nonlinear optical susceptibility of crystalline oxide yttria-stabilized zirconia显示文摘Nonlinear all-optical technology is an ultimate route for the next-generation ultrafast signal processing of optical communication systems.New nonlinear functionalities need to be implemented in photonics,and complex oxides are considered as promising candidates due to their wide panel of attributes.In this context,yttria-stabilized zirconia(YSZ)stands out,thanks to its ability to be epitaxially grown on silicon,adapting the lattice for the crystalline oxide family of materials.We report,for the first time to the best of our knowledge,a detailed theoretical and experimental study about the third-order nonlinear susceptibility in crystalline YSZ.Via self-phase modulation-induced broadening and considering the in-plane orientation of YSZ,we experimentally obtained an effective Kerr coefficient of n2YSZ=4.0±2×10^-19 m^2·W^-1 in an 8%(mole fraction)YSZ waveguide.In agreement with the theoretically predicted n2YSZ=1.3×10^-19 m^2·W^-1,the third-order nonlinear coefficient of YSZ is comparable with the one of silicon nitride,which is already being used in nonlinear optics.These promising results are a new step toward the implementation of functional oxides for nonlinear optical applications. | GUILLAUME MARCAUD SAMUEL SERNA KARAMANIS PANAGHIOTIS CARLOS ALONSO-RAMOS XAVIER LE ROUX MATHIAS BERCIANO THOMAS MAROUTIAN GUILLAUME AGNUS PASCAL AUBERT ARNAUD JOLLIVET ALICIA RUIZ-CARIDAD LUDOVIC LARGEAU NATHALIE ISAC ERIC CASSAN SYLVIA MATZEN NICOLAS DUBREUIL MICHEL RERAT PHILIPPE LECOEUR LAURENT VIVIEN | 2020 | Photonics Research2020，8，2： | 0 |
