21. Laboratory soft x-ray microscopy and tomography
Sammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER
22. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy
Sammanfattning : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. LÄS MER
23. Dissipative Kerr solitons in normal dispersion waveguides
Sammanfattning : The microresonator comb (microcomb) is a laser source which generatesequally spaced coherent lines in the spectral domain. Having a miniaturefootprint and the potential of being low cost, it has attracted attention inmultiple applications. LÄS MER
24. VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects
Sammanfattning : The majority of global data communication is taking place within data centers where data is stored and processed and where the largest part of the power used for global networking is consumed. With the rapidly increasing use of Internet-based applications and services, data centers are equipped with a larger number of servers and switches requiring higher bandwidth connectivity. LÄS MER
25. Microcombs for ultrafast optical interferometry
Sammanfattning : The optical frequency comb has revolutionized the field of laser spectroscopy. This type of laser, characterized by an array of uniformly spaced and coherent laser lines, finds promise in photonic platforms for the integration of chip-scale spectrometers. LÄS MER
