  1. 21. 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

  3. 22. Fiber-based Stray Light Suppression in Spectrometers

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

    Author : Miaoxin Gong; [2017]
    Keywords : spectroscopy; spectrometer; stray light; fiber optics; Periodic Shadowing; lock-in analysis; Raman spectroscopy; Physics and Astronomy;

    Abstract : Stray light is known as strong interference in spectroscopic measurements. With the creation of a novel kind of customized fibers, manufactured by the fiber optics group in Jena, Germany, a general experimental solution to this problem is possible. READ MORE

  4. 23. Evaluation of future trial embankments : A study of measurement methods to apply on Lampen test embankments, Kalix, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Robin Holmström; Dmytro Yakubov; [2017]
    Keywords : Lampen; Future Embankments; Evaluation; Soil; Softsoil; Geotechnical Engineering;

    Abstract : At the Lampen site outside of Kalix, Sweden two embankments with heights 1,5m and 2m have been built to study and test the properties of sulfide soil that is located in the Gulf of Bothnia coastal areas. In this master thesis investigations have been done on what more could be done at the Lampen site today concerning new technics, measurements, observations and calculations etc. READ MORE

  5. 24. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

    Author : Alexander Bengtsson; [2017]
    Keywords : Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Abstract : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. READ MORE

  6. 25. Automatic Measurement Setup for Characterization of On-Chip Tunable Grating Couplers

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Kristian Wahlqvist; Felix Caesar; [2017]
    Keywords : ;

    Abstract : Grating couplers are used for coupling betweenoptical fibers and on-chip silicon photonics waveguides. Efficientfiber-to-chip coupling is elemental in in the development ofphotonics, making the process of evaluating new grating couplerdesigns vital. READ MORE
