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. Stacked Dual Narrowband Organic Near-Infrared Photodetectors

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Yazhong Wang; [2017]
   Keywords : Near-infrared; photodetectors; CT states; Fabry-Perot resonant cavity; resonant cavity enhancement; tunability; full width at half maximum;

   Abstract : Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. READ MORE
