TL;DR: In this paper, the authors present a review of the NTT HiS technology and its application to integrated-optic components such as optical beam splitters, optical switches, wavelength-division multi/demultiplexers and optical frequency division multi/multiplexers.
Abstract: A marriage of optical fibre fabrication technology and LSI microfabrication technology gave birth to fibre-matched silica waveguides on silicon: thick glass layers of high-silica-content glass are deposited on silicon by flame hydrolysis, a method originally developed for fibre preform fabrication. Silica channel waveguides are then formed by photolithographic pattern definition processes followed by reactive ion etching. This ‘high silica (HiS) technology’ offers the possibility of integrating a number of passive functions on a single silicon chip, as well as the possibility of the hybrid integration of both active and passive devices on silicon. This paper reviews the NTT HiS technology and its application to integrated-optic components such as optical beam splitters, optical switches, wavelength-division multi/demultiplexers and optical frequency-division multi/demultiplexers. The clear and simple waveguide structures produced by the HiS technology make it possible to design and fabricate these components with high precision and excellent reproducibility.

TL;DR: In this paper, the authors derived analytical expressions for the scattering loss in planar optical waveguides whose surface roughness can be described by an exponential or Gaussian autocorrelation function.
Abstract: We derive analytical expressions for the scattering loss in planar optical waveguides whose surface roughness can be described by an exponential or Gaussian autocorrelation function. Our results show, for the first time, the explicit dependence of the loss coefficient on all the waveguide parameters. In addition, we show that for any waveguide there is a simple upper limit for the scattering loss.

TL;DR: Cascading is the process by which the exchange of energy between optical beams interacting via second order nonlinearities leads to various effects such as nonlinear phase shifts, the generation of new beams, all-optical transistor action, the formation of soliton-like (solitary) waves, etc as mentioned in this paper.
Abstract: Cascading is the process by which the exchange of energy between optical beams interacting via second order nonlinearities (χ(2)) leads to various effects such as nonlinear phase shifts, the generation of new beams, all-optical transistor action, the formation of soliton-like (solitary) waves, etc. Here we review the fundamentals of the processes and discuss experimental verification of the effects and various related applications.

TL;DR: In this paper, the authors provide an exhaustive account of current trends concerning the physics, the mechanics and the applications involved in laser shock processing (LSP) and present some general and specific data regarding the physical principles of laser shock.
Abstract: Developed since the beginning of the 1970s in the United States (Battelle, Columbus), laser shock processing (LSP) is being extensively studied in France in order to improve the mechanical properties of metallic surfaces of dense or porous materials. This paper reviews the considerable data on LSP which has been obtained in recent years and provides an exhaustive account of current trends concerning the physics, the mechanics and the applications involved. After presenting some general and specific data regarding the physical principles of laser shock (laser system, plasma physics, pressure generation, physical limits) and mechanical effects induced (experimental and theoretical) on different materials, the efficiency of the process is illustrated through two potential industrial applications linked with modifications of surface states: fatigue and wear resistance of metals. Experience with LSP applications shows that, because it uses safe surface geometries and provides greater affected depths, LSP is about to emerge as a real alternative to classical treatments.

TL;DR: In this article, the phase singularities in an optical field appear as isolated dark spots and can be generated in active laser cavities or by computer generated holograms, and detection and categorization of these singularities can easily be achieved either by interferometry or Fourier transform pattern recognition using a computer-generated hologram.
