  1. 1. Optical Fiber Phase Noise Cancellation for Slow Light Crystal Cavity Locking

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

    Author : Mohammad Tasnimul Haque; [2016]
    Keywords : Optical Fiber; Phase Noise; Slow Light; Stabilisation; Quantum Information; Quantum Optics; Optical Clocks; Physics and Astronomy;

    Abstract : Recent developments in the field of optical clocks and quantum information have fueled the necessity for both fiber phase noise cancellation and laser stabilisation. The Quantum Information group at Lund University is conducting research on quantum computation experiments based on rare earth ion doped crystals and also application of slow light effects induced by spectral hole burning in these rare earth ion doped crystals.

  3. 2. The Timing and Fast Control Demonstrator

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Jiheng Chen; Vasileios Filos; [2016]
    Keywords : ;

    Abstract : In this thesis, the feasibility of an FPGA to host a system for generating and distributing clocks as well as distributing synchronous and asynchronous commands is tested. This system will be an imitation of the SHiP (Search for Hidden Particle) DAQ (Data Acquisition) system led by CERN. READ MORE

  4. 3. Ultra-stable frequency transfer using optical fibers

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

    Author : Simon Preutz; [2016]
    Keywords : Optics; optical fibers; stability; time; optical clocks; control.; Technology and Engineering;

    Abstract : A new era of precise time measurement came with the atomic clock. The technology is vital to navigations systems like GPS and to accurate physical measurements. READ MORE

  5. 4. Mission Concept for a Satellite Mission to Test Special Relativity

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Volkan Anadol; [2016]
    Keywords : BOOST; Special Relativity; Kennedy Thorndike; Eclipse duration; Ground visibility; Downlink feasibility; 3-axis stabilization; Spin stabilized satellite; Solar array estimation; Battery size estimation.;

    Abstract : In 1905 Albert Einstein developed the theory of Special Relativity. This theory describes the relation between space and time and revolutionized the understanding of the universe. While the concept is generally accepted new experimental setups are constantly being developed to challenge the theory, but so far no contradictions have been found. READ MORE

  6. 5. Characterization of a Zeeman Slower Designed for a 87 Sr Optical Clock

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

    Author : Jonas Olsson; [2015]
    Keywords : metrology; time; frequency; atomic clock; optical clock; strontium; frequency comb; zeeman slower; arduino; Physics and Astronomy;

    Abstract : Optical clocks will potentially become the new frequency standard for the SI-definition of the second. Many national metrology institutes around the world have already implemented different versions of such clocks and others are in process of doing so. At SP Technical Research Institute of Sweden, this process has recently begun. READ MORE
