    Abstract : Seediq is an Austronesian language spoken in Taiwan. It has several characteristics which are typologically unusual but typical for Austronesian languages. VOS word order, subject-focus (i.e. READ MORE

  4. 7. Spectral control of lasers and optical parametric oscillators with volume Bragg gratings

    Author : Björn Jacobsson; Fredrik Laurell; Uwe Morgner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volume Bragg gratings; single-longitudinal-mode laser; laser tuning; erbium; neodymium; ytterbium; nonlinear optics; optical parametric oscillator; KTP; tunable optical parametric oscillator; narrowband optical parametric oscillator; Physics; Fysik;

    Abstract : I den här avhandlingen visas hur lasrar och optiska parametriska oscillatorer (OPO:er) kan styras spektralt med hjälp av volymbraggitter. Volymbraggitter utgörs av ett periodiskt varierande brytningsindex som skrivits i ett fototermorefraktivt glas. READ MORE

    Abstract : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. READ MORE

  6. 9. Optical Parametric Devices in Periodically Poled LiTaO3

    Author : Martin Levenius; Katia Gallo; Valdas Pasiskevicius; Giuseppe Leo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; parametric processes; frequency downconver-sion; quasi-phase matching; LiTaO3; broadband downconversion; quadratic cascading; nonlinear photonic crystals; twin-beam generation;

    Abstract : Optical parametric frequency conversion based on quasi phase matching (QPM) in nonlinear optical crystals is a powerful technique for generating coherent radiation in wavelength ranges spanning from the mid-infrared (mid-IR) to the blue, displaying low thermal load and high efficiency.This thesis shows how QPM in one- (1D) or two-dimensional (2D) lattices can be employed to engineer novel devices for parametric downconversion in the IR, af-fording freedom in designing both spectral and angular properties of the parametric output.

  7. 10. Parametric interactions with signals and the vacuum

    Author : Michael Roger Andre Simoen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vacuum; circuit-QED; interferometer; SQUID; dynamical Casimir effect; multimode resonator; pumpistor; mode conversion; superconducting circuits; parametric amplification;

    Abstract : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. READ MORE
