  1. 1. Nonlinear intrachannel distortion in high-speed optical transmission systems

    Author : Pontus Johannisson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; all-optical regeneration; nonlinear optics; fiber optics; self-phase modulation; cross-phase modulation; ghost pulses; intrachannel four-wave mixing; timing jitter;

    Abstract : The Kerr nonlinearity in optical fibres tends to generate signal distortion in dispersion-managed fibre-optic communication systems. Within a wavelength channel, the resulting intrachannel effects are timing jitter, i.e. READ MORE

  3. 3. Mid- and near-infrared NICE-OHMS techniques for ultra-sensitive detection of molecules in gas phase

    University dissertation from Umeå : Umeå universitet

    Author : Thomas Hausmaninger; Umeå universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectrometry; NICE-OHMS; trace gas detection; acetylene; methane; isotopologues; near-infrared; mid-infrared; shot-noise; optical parametric oscillator; Technical Physics; teknisk fysik med inriktningen mikrosystemteknik;

    Abstract : Noise-immune cavity-enhanced optical heterodyne molecular spectrometry (NICE-OHMS) is a technique for ultra-sensitive detection of molecular absorption and dispersion. For highest performance, the technique combines cavity enhancement (CE) with frequency modulation (FM); while the former increases the effective interaction length between the light and the analyte by several orders of magnitudes, the latter removes the in-coupling of 1/f noise and makes the signals background free.

  4. 4. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    University dissertation from Department of Electroscience, Lund University

    Author : Gang Xu; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Abstract : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. READ MORE
