1. 1. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

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

   Author : Jannek Hansen; [2021]
   Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

   Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

3. 2. Live 3D imaging quantum LiDAR

   University essay from KTH/Tillämpad fysik

   Author : Theodor Staffas; [2021]
   Keywords : lidar; otdr; snspd; lidar; otdr; snspd;

   Abstract : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. READ MORE

4. 3. Shape Distortion Analysis of Self-Reinforced Poly(ethylene terephthalate) Composites : The PETrifying reality!

   University essay from KTH/Lättkonstruktioner

   Author : Calle Eliasson; [2016]
   Keywords : ;

   Abstract : Composite components with a V-shaped geometry have been manufactured through compression moulding of fabrics based on self-reinforced poly(ethylene terephthalate). The fabrics were subjected to a set of predetermined degrees of stretching during manufacturing with the intent to investigate its effects on shape distortions in terms of spring-in and warping.

5. 4. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

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

   Author : Karolina Dorozynska; [2015]
   Keywords : Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

   Abstract : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. READ MORE

6. 5. Experimental set-up for near infrared fluorescence measurements during surgery

   University essay from Biomedicinsk instrumentteknik; Tekniska högskolan

   Author : Pascal Behm; [2013]
   Keywords : ;

   Abstract : In case a tumour grows in a tissue close to the lymphatic system, biopsies of the first draining lymph nodes connected to the tumour, also known as sentinel lymph nodes, allow determining if the cancer has already metastasized. Lymph node mapping is used in oncology surgery to find the patients lymph nodes connected to the tumour. READ MORE
