1. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE

2. Investigation of phase conjugation for medical imaging
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : With the development of extremely precise spectral filters based on spectral hole burning and slow light effects, the idea of their implementation in an Ultrasound Optical Tomography (UOT) medical imaging technique arose. Simulations have shown that the resulting Contrast-to-Noise (CNR) ratio is fairly good at depths up to 5 cm but decreases dramatically when probing deeper in tissue. READ MORE

3. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking
University essay from Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysikAbstract : 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

4. Development of a Tunable Frequency Shift Filter Using a Praseodymium Doped Y2SiO5-Crystal
University essay from Lunds universitet/Fysiska institutionenAbstract : In this thesis, a tunable frequency shift filter (FSF) with a 1 ~ 2 MHz passband created in a praseodymium doped Y2SiO5-crystal using a special hole burning technique is developed and tested. The FSF is able to shift the frequency of its passband and the light passing through the passband by applying an external electric field, where the frequency shift is proportional to the applied field.

5. Optical Fiber Phase Noise Cancellation for Slow Light Crystal Cavity Locking
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikAbstract : 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.
