1. 16. Integration of III-V light sources for silicon photonics applications

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Louise Laurenius; [2016]
   Keywords : III-V integration; multiquantum well lasers; lateral current injection; silicon photonics; Technology and Engineering;

   Abstract : During the last decades, there have been tremendous improvements in Silicon-based transistor technologies such as operational speed increase as well as size and cost reduction. However, the bandwidth in modern processors is significantly limited by the data transfer in the metallic interconnects. READ MORE

3. 17. Silicon photonics based MEMS tunable polarization rotator for optical communications

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Sandipan Das; [2016]
   Keywords : Silicon photonics; MEMS; Tunable polarization rotator; Polarization beam splitter; Kiselfotonik; MEMS; Flytande polarisationsrotator; polarisationsstr°aldelare;

   Abstract : There has been a huge surge in data traffic all over the world due to the rise of streamingmedia services and connected devices. The current demand in data traffic has alreadypushed the optical fiber in the internet architecture to the network edges and the trend isto push it as close as possible, to the CPU. READ MORE

4. 18. Diffuse Reflectance Spectroscopy: Using a Monte Carlo method to determine chromophore compositions of tissue

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

   Author : Lisa Kobayashi Frisk; [2016]
   Keywords : Photonics; Biophotonics; Diffuse Reflectance; Spectroscopy; Monte Carlo; Diffusion; Physics and Astronomy;

   Abstract : In this work, inverse diffusion equation and Monte Carlo methods are used in conjunction with diffuse reflectance spectroscopy to develop a protocol for evaluating the chromophore compositions of tissue mimicking liquid phantoms. A novel two spectrometer system is used which provides real time calibration of any intensity fluctuations of the light source. READ MORE

5. 19. High resolution imaging of GaAs nanowires

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

   Author : Andreas Johansson; [2015]
   Keywords : Scanning Tunneling Microscopy; STM; Nanowire; Gallium Arsenide; GaAs; Semiconductor; Atomic structure; Morphology; Nanoelectronics; Heterostructure; Physics and Astronomy;

   Abstract : Semiconductor nanowires (NWs) are expected to be the new building blocks in electronics and photonics, but improved understanding of the nanowire surfaces and electronic properties are required to realize it. In this bachelor thesis, wurtzite (Wz)-zincblende (Zb) axial heterostructure GaAs nanowires are studied using scanning tunneling microscopy and spectroscopy. READ MORE

6. 20. Generation of Short Intense Terahertz pulses Through Optical Rectification

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

   Author : Carl Ekström; [2015]
   Keywords : Terahertz; THz; Optical Rectification; OR; Photonics; Optics; LiNbO3; Physics and Astronomy; Technology and Engineering;

   Abstract : The lack of sources that generates intense THz pulses have in many years limited the field of THz science. Until recently intense THz pulses have been hard to generate using nonlinear crystals such as Lithium Niobate (LiNbO3) with high efficiency. READ MORE
