  1. 6. All-optical nonlinearity mitigation in fiber-optic communications

    Författare :Henrik Eliasson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber-optic communications; phase-sensitive amplifiers; optical phase conjugation; nonlinear optics;

    Sammanfattning : The two main factors limiting the data throughput in modern fiber-optic communication links are the noise added by amplifiers and the nonlinear response of the optical fiber due to the Kerr effect. Today there are communication systems operating remarkably close to the limits set by these two factors. LÄS MER

  3. 7. Plasmonic Nanostructures for Molecular Spectroscopy

    Författare :Björn Brian; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SEF; DNA; EBL; Nanoparticles; rhodamine 6G; biosensors; SERS; fluorescence;

    Sammanfattning : This thesis focuses on the fabrication, characterization and utilization of nanostructures for chemical sensing and optical enhancement processes.Noble metal nanostructures can support localized surface plasmon resonances (LSPRs), which amplify the strength of the electromagnetic field close to the structures.
