1. 16. Photoluminescence-based characterization of bioengineered nanovesicles and erbium emitters

   Författare :Maryam Sanaee; Katia Gallo; Jerker Widengren; Martin Hof; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineered nanovesicles; Coincident fluorescent burst analysis; Drug loading; Erbium emitters; Lithium niobate; Photoluminescence.; Bioingenjörskonstruerade nanovesiklar; Analys av sammanfallande fluorescerande blossteknik; Läkemedelslastning; Erbium-emitterare; Lithium niobate; Fotoluminiscens.; Biologisk fysik; Biological Physics; Optics and Photonics; Optik och fotonik;

   Sammanfattning : In recent decades, photoluminescence properties of single molecules and ions have opened new possibilities for studies on smaller size scales, below the light-diffraction limit. In this thesis, the advantages of such single photon emitters were harnessed and studied mainly in the field of biophysics, but also, in investigations within solid state photonics. LÄS MER

3. 17. Design, Fabrication, and Evaluation of High-Speed Vertical-Cavity Surface-Emitting Lasers

   Författare :Petter Westbergh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semiconductor laser; high speed modulation; fabrication; vertical-cavity surface-emitting lasers VCSELs ;

   Sammanfattning : The vertical-cavity surface-emitting laser (VCSEL) is a low cost light source with inherent high speed capabilities. These properties, along with low power consumption and a circular output beam, have made the VCSEL a well established component in digital communication networks, particularly in short reach optical data transmission where links consisting of GaAs-based 850nm VCSELs and multimode fiber have become the standard solution.

4. 18. Selective Epitaxy of Indium Phosphide and Heteroepitaxy of Indium Phosphide on Silicon for Monolithic Integration

   Författare :Fredrik Olsson; Sebastian Lourdudoss; Shigeya Naritsuka; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor Physics; Semiconductor physics; Halvledarfysik;

   Sammanfattning : A densely and monolithically integrated photonic chip on indium phosphide is greatly in need for data transmission but the present day’s level of integration in InP is very low. Silicon enjoys a unique position among all the semiconductors in its level of integration. LÄS MER

5. 19. Advanced Nanofabrication for Novel Plasmonic Biosensors

   Författare :Francesco Mazzotta; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Photo diode; Localized surface plasmon resonance; Bioanalytical sensing; Nanopores.; Solar cell; Nanofabrication; Nanodisks; Nanoplasmonics; Biosensor;

   Sammanfattning : There is an increasing interest in the development of novel biosensors in the foreseeable future.The impact on society of diseases connected to the aging of population, for example infectiousdiseases, cancer and Alzheimer’s disease, has the potential of increasing the running costs ofwelfare over a sustainable threshold already within a few years.

7. 20. Frequency comb Brillouin microscopy

   Författare :Felipe Ademir Alemán Hérnandez; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brillouin light scattering; optics; spinwave spectroscopy; phonon spectroscopy; microscopy; Fabry-Perot interferometer; Frequency comb;

   Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER
