  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. Pre-study of optical LED units for shunting signals

    University essay from KTH/Hälsoinformatik och logistik

    Author : Tobias Adolfsson; Axel Dellenby; [2021]
    Keywords : LED - Light Emitting Diode; Booster Converter; MLCC - Multi-layer capacitor; ESR - Equivalent Serie Resistance; OU - Optical Unit; Reactive compensation; LED - lysdiod; step-up omvandlare; MLCC - flerskiktskeramisk kondensator; ESR - ekvivalent serie motstånd; OU - optiskt enhet; reaktiv kompensering;

    Abstract : Alstom wanted to investigate the possibility of adapting its light emitting diode (LED) technology for shunting signals in train traffic. The LED technology uses 50V, but Alstom wants to adapt it for 12V. The LED technology is energy efficient but needs to be adapted for existing signal interlocking by drawing a higher current.

  4. 3. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sefik Güler; Agbai Randolph Agwu; [2020]
    Keywords : Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Abstract : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. READ MORE

  5. 4. Best PAL : Ball Exercise Sound Tracking PAL

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Axel Sundkvist; Joakim Hellberg; [2018]
    Keywords : mechatronics; microcontroller; sound source localization; wireless communication; DC motor controlling; mekatronik; mikrokontroller; ljudlokalisering; trådlös kommunikation; likströmsmotorstyrning;

    Abstract : The PAL (Practise and Learn) Original is a ball boardconsisting of three wooden boards placed in a triangle, developedto practise football players’ passing ability and firsttouch. The former Swedish international footballer JessicaLandstr¨om observed that these ball boards can, if they areimproved, help footballers to develop even more skills whilepracticing alone. READ MORE
