  1. 16. Modeling the cavity dispersion in cavity-enhanced optical frequency comb Fourier transform spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adrian Hjältén; [2018]
    Keywords : ;

    Abstract : Cavity enhanced optical frequency comb spectroscopy is a technique that allows for quick and sensitive measurements of molecular absorption spectra. Locking the comb lines of an optical frequency comb to the cavity modes of an enhancement cavity and then extracting the spectral information with a Fourier transform spectrometer grants easy access to wide segments of absorption spectra.

  3. 17. Implementation and Evaluation of Two 512-Tap Complex FIR Filter Architectures for Compensation of Chromatic Dispersion in Optical Networks

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Anton Kovalev; [2017]
    Keywords : DSP; VHDL; FIR; MATLAB; Digital communication; Optical networks;

    Abstract : Filtering is an important part of digital processing, since the applications often require a change of features of a digital or analog signal. A digital filter is a device or a system that removes or alters certain parts of a signal. READ MORE

  4. 18. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : David Frantz; [2017]
    Keywords : scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

    Abstract : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. READ MORE

  5. 19. Evaluation of white-light generation as possible seed for a mid-infrared optical parametric chirped pulse amplifier

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Chuang Lu; [2017]
    Keywords : nonlinear linear optics; ultrafast optics; Mid-infrared generation; near-infrared; Optical parametric amplification; Optical Parametric Chirped-pulse Amplification; supercontinuum generation; white-light generation; laser induced filamentation; Dispersion-scan; nonlinear propagation; Physics and Astronomy;

    Abstract : White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broadening as well as high tolerance to optical damage.

  6. 20. Statistical Analysis of Equalization Enhanced Phase Noise in Coherent Fiber Optical Communications

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Thomas Gaudy; [2016]
    Keywords : ;

    Abstract : Coherent optical communications increase the receiver sensitivity and the total capacity. Together with high speed digital signal processing (DSP), compensation for linear transmission impairments (chromatic dispersion, polarization mode dispersion and phase noise) can be achieved.
