  1. 1. Nonlinear mode coupling and parametric amplification with superconducting kinetic inductance

    University essay from KTH/Tillämpad fysik

    Author : Daniele Lopriore; [2022]
    Keywords : Quantum technology; microwave engineering; nanofabrication; parametric amplifiers; multimode entanglement; kinetic inductance; Kvantteknologi; mikrovågsteknik; nanotillverkning; parametriska förstärkare; multimodentrassling; kinetisk induktans;

    Abstract : We investigate the resonant characteristics of superconducting meandering nanowires to design a nonlinear kinetic inductance traveling-wave parametric amplifier. The devices are patterned out of 15 nm thick NbTiN films. They consist of a coplanar waveguide, that shrinks into 100 nm wide meandering nanowires. READ MORE

  3. 2. Application of Twist Symmetry to a Cylindrical Dielectric Waveguide

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

    Author : Kwinten Van Gassen; [2020]
    Keywords : ;

    Abstract : The application of higher order symmetry to waveguide design is an active field and is showing evidence of improvement over traditional waveguide designs. There are two forms of higher symmetry: glide symmetry and twist symmetry. READ MORE

    Abstract : This report examines fiber optic cables and their ability to transmit data when exposed to fire conditions. By performing various experiments the study aims to widen the knowledge base in an area that at the moment is scarce in information. READ MORE

  6. 5. Spatial mode engineering in mid-infrared optical parametric oscillators

    University essay from KTH/Laserfysik

    Author : Charlotte Liljestrand; [2011]
    Keywords : ;

    Abstract : The purpose of this thesis was to investigate the possibilities of enhancing the temporal and spatial coherence of parametric devices in the mid-infrared spectrum by exploiting inherent coherence selection of Bessel beams. Several optical parametric oscillators (OPO) were constructed and characterized for various types of resonators and pump lasers. READ MORE
