  1. 11. Transmission characterization of fiber Bragg gratings arrays for intracavity spectral control of a 1.5 micrometer fiber laser

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hu Leo Qiyuan; Pontus Jäderholm; [2021]
    Keywords : ;

    Abstract : This thesis aims to investigate whether a fiber Bragg grating array (FBGA) can be designed to reduce the bandwidth of light from a 1.5 µm fiber laser while the distances between the fiber Bragg gratings are in the 10-20 cm range. READ MORE

  3. 12. Live 3D imaging quantum LiDAR

    University essay from KTH/Tillämpad fysik

    Author : Theodor Staffas; [2021]
    Keywords : lidar; otdr; snspd; lidar; otdr; snspd;

    Abstract : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. READ MORE

  4. 13. Development of Next-Generation Optical Tweezers : The New Swiss Army Knife of Biophysical and Biomechanical Research

    University essay from Umeå universitet/Institutionen för fysik

    Author : Daniel Nilsson; [2020]
    Keywords : optical tweezers; optical fiber tweezers; optical fiber; optical trapping; manipulation; optical force; cell trapping; biophysical; physicochemical; biomechanical; research; next-generation; raman spectroscopy; holographic optical tweezers;

    Abstract : In a time when microorganisms are controlling the world, research in biology is more relevant than ever and this requires some powerful instruments. Optical tweezers use a focused laser beam to manipulate and probe objects on the nano- and microscale. READ MORE

  5. 14. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

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

    Author : Sergio Steven Gutierrez; [2020]
    Keywords : QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Abstract : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. READ MORE
