  2. 1. InP based Micromechanics for Vertical-Cavity Micro-Opto-Electro-Mechanical Systems

    Author : Martin Strassner; KTH; []
    Keywords : MOEMS; vertical-cavity; InP; DBR; epitaxy; semiconductor processing; micromechanics; wavelength tunable devices; long-wavelength;

    Abstract : During the past decade, the amount of transmitted data hasbeen boosted due to an increasing use of the World Wide Web(WWW), video and audio transmissions. In the late 90s, thetraditional technology using twisted copper cables was nolonger capable to provide enough transmission capacity for theconstantly increasing data traffic. READ MORE

  6. 4. Tunable superconducting transmissionline resonator for qubit coupling

    Author : Martin Sandberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fast tuning; superconductivity; transmission line; SCB; Josephson inductance.; Frequency tunable resonator; SQUID; CPW; aluminium;

    Abstract : In this licentiate thesis design, fabrication, and measurements of tunable superconducting microwave transmission line resonators are described. The resonators are of quarter wavelength type were the tuning is achieved by changing one of the boundary conditions of the resonator through a tunable impedance. READ MORE
