  2. 16. Nanowire Superinductors

    Author : David Niepce; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Disordered Superconductors; Superinductance; Superinductor; Resonator; Nanowire; TLS;

    Abstract : In this thesis, we demonstrate that a disordered superconductor with a high kinetic inductance can realize a low microwave loss, non-dissipative circuit element with an impedance greater than the quantum resistance (Rq = h/4e^2 = 6.5kΩ). READ MORE

  4. 17. Integrated Optical Slot-Waveguide Ring Resonator Sensor Arrays for Lab-on-Chip Applications

    Author : Kristinn Björgvin Gylfason; Göran Stemme; Hans Sohlström; Peter Bienstman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosensor; label-free biosensing; ring resonator; optical waveguide; lab-on-a-chip; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik; Photonics; Fotonik;

    Abstract : This thesis treats the development of an integrated optical sensor array. The sensors are slot-waveguide ring resonators, integrated with on-chip surface grating couplers and light splitters, for alignment tolerant, real-time, refractive index sensing, and label-free biosensing.

  5. 18. Grating-Coupled Surface-Emitting Lasers -- Circular and Unstable-Resonator Geometries

    Author : Sigurgeir Kristjánsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser beam focusing; grating coupled surface emitters; simulation; unstable resonator lasers; surface-emitting lasers; integrated optics; gratings; circular gratings; BPM simulations; laser resonators; semiconductor lasers; optical planar waveguide couplers; electron beam lithography;

    Abstract : This thesis deals with research in the field of grating-coupled surface-emitting lasers. The emphasis has been to study the modal behavior of lasers with two different resonator geometries: circular resonators and tapered unstable-resonators. READ MORE

  7. 20. Design, Fabrication and Characterization of Microwave Passive Devices on Liquid Crystal Polymer Substrates

    Author : Xia Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-planar waveguide; parallel-coupled line resonator; dual-mode ring resonator; millimeter wave; ultra-wideband; Bandpass filter; liquid crystal polymer substrate; printed monopole antenna;

    Abstract : For microwave/millimeter (mm)-wave systems’ applications, as frequency is moving towards higher and higher bands, materials and integration technologies are witnessing higher performance demands and constraints. The materials presently used as mm-wave substrates are either expensive or show unsatisfactory performance. READ MORE
