1. 1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

   University essay from KTH/Tillämpad fysik

   Author : Alexandros Bampis; [2023]
   Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

   Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE

3. 2. Single Photon LSCM in the NIR Range

   University essay from KTH/Tillämpad fysik

   Author : Klara Wallenbro; [2022]
   Keywords : LSCM; NIR; SNSPD; LSCM; NIR; SNSPD;

   Abstract : In this thesis a near-infrared laser scanning confocal microscope (NIR-LSCM) is built to operate with optimal performance at 1550nm in combination with simultaneous LED light imaging at 970nm. For detection, a camera equipped with a complementary metal oxide semiconductor (CMOS) sensor and a superconducting nanowire single photon detector (SNSPD) are used for the LED part and the LSCM part, respectively.

4. 3. Optical Detection and Altitude Estimation of Power Lines Relative to a UAV

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

   Author : Carl Daniel Ahlberg; [2020]
   Keywords : ;

   Abstract : Inspection of power lines is a crucial activity to locate the source of power outages or to preemptively stop them. Visual inspection methods using optical cameras attached to Unmanned Aerial Vehicles (UAV) have become increasingly popular due to cheap operating costs, large areal coverage and the wide availability of these platforms.
