1. InP based Micromechanics for Vertical-Cavity Micro-Opto-Electro-Mechanical Systems
Sammanfattning : 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. LÄS MER
2. Bright and strain-tunable semiconductor quantum dot devices
Sammanfattning : Optically active semiconductor quantum dots have proven to be excellent single- and entangled-photon sources, with applications in quantum optics and quantum photonics. These sources are considered crucial in the development of future photonic quantum technology, such as quantum communication, quantum computation and quantum metrology. LÄS MER
3. Comb-based Characterization of Photonic Devices
Sammanfattning : Integrated photonics has been one of the fastest-growing fields in science. Measuring photonic devices in amplitude and phase (i.e. complex response) provides insight into their performance. LÄS MER
4. Tunable superconducting transmissionline resonator for qubit coupling
Sammanfattning : 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. LÄS MER
5. Advanced characterization techniques of photonic devices with frequency combs
Sammanfattning : Integrated photonics has witnessed remarkable progress in the last decades. Measuring photonic devices in amplitude and phase provides insight into their performance. Swept wavelength interferometry is a prominent technique for the broadband characterization of the complex response. LÄS MER
