1. 11. 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. 12. Interface Roughness in Quantum Cascade Lasers

   University essay from Lunds universitet/Matematisk fysik

   Author : Kasparas Antanas Krivas; [2015]
   Keywords : Quantum Cascade Lasers; Interface Roughness; Modeling; Physics and Astronomy;

   Abstract : The quantum cascade laser (QCL) is a solid state device capable of generating the coherent mid-infrared and terahertz radiation. It is made from layers of different semiconducting materials. This layered structure gives rise to sub-bands, that are employed to achieve charge inversion necessary for lasing. READ MORE

4. 13. Setup for Micro Photo- and Electro-Luminescence of Optoelectronic Device Structures

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Yuxuan Sun; [2015]
   Keywords : Photoluminescence; Photoluminescence setup; Electroluminescence; Optoelectronic device;

   Abstract : Photoluminescence (PL) is an optical emission induced by photon absorption in a material where electrons are excited from the ground state to excited states, then relax to the lowest excited states and recombine radiatively. The PL emission provides vital information on bandgap energy, material purity and crystal quality. READ MORE

5. 14. Design and implementation of 1GbpsLaser Ethernet Transceiver (LET) for Free-Space Optical communications

   University essay from KTH/Rymd- och plasmafysik

   Author : JORGE PACHECO LABRADOR; [2014]
   Keywords : ;

   Abstract : Free Space Optical (FSO) communications are an emerging technology. Multiple resources around the world are being dedicated to the study and implementation of associated technologies. The possibility of high data rates, lower masses and more power efficient antennas are the expected advantages of these systems. READ MORE

6. 15. Investigation of the chirp properties of DFB-EAM’s for high speed baseband and RoF transmission links

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Miguel Olmedo Iglesias; [2012]
   Keywords : ;

   Abstract : The ever increasing bandwidth demands driven by an explosion in the mobile device market calls for more and more optical and wireless convergence due to the ability of optical communication systems to transport larger amounts of information to longer distances. Optical modulators are in charge of performing the electrical-to-optical domain conversion, which place them as one of the critical components in optical communication systems. READ MORE
