  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

  5. 3. Engineering and detecting microwave photons

    Author : Sankar Raman Sathyamoorthy; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwave photon detection; Quantum optics; open quantum systems.; tunable cavity; cross-Kerr effect; circuit QED;

    Abstract : Microwave quantum optics using superconducting circuits, also known as circuit QED, is a recent and promising field to study light-matter interactions at the fundamental level. In this field, artificial atoms made of superconducting elements interact with microwave photons routed through one dimensional transmission lines. READ MORE

  6. 4. Continuously tunable narrow-linewidth fiber lasers

    Author : Xiong Yang; Valdas Pasiskevicius; Fredrik Laurell; Magnus Engholm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber laser; Optik och fotonik; Optics and Photonics;

    Abstract : Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber lasers. READ MORE

  7. 5. MM-wave integrated RF-MEMS tunable cavity resonators, filters and ultra-low phase-noise oscillators

    Author : Dragos Dancila; Isabelle Huynen; Universite catholique de Louvain (UCL); []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Within the Microelectronics Industry, the core research is focused on the realization of the Moore's law, which states that circuit density doubles every 24 months, shaping the framework of the More of Moore paradigm. However, Moore's law is expected to end, as devices are reaching limitations inherent to the approach of the atomical dimensions. READ MORE
