1. Frequency comb Brillouin microscopy
Sammanfattning : Brillouin light scattering (BLS), an almost a century-old technique, has evolved into a powerful and versatile method to study acoustic and magnetic phenomena down to the nanometer size scale. Presently, BLS can be applied in fields as diverse as acoustics, spintronics, geosciences, and biophysics. LÄS MER
2. Optical Frequency Comb Fourier Transform Spectroscopy
Sammanfattning : Fourier transform spectroscopy (FTS) based on optical frequency combs is an excellent spectroscopic tool as it provides broadband molecular spectra with high spectral resolution and an absolutely calibrated frequency scale. Moreover, the equidistant comb mode structure enables efficient coupling of the comb to enhancement cavities, yielding high detection sensitivity. LÄS MER
3. Cavity enhanced optical sensing
Sammanfattning : An optical cavity comprises a set of mirrors between which light can be reflected a number of times. The selectivity and stability of optical cavities make them extremely useful as frequency references or discriminators. LÄS MER
4. High-capacity short-reach optical communications
Sammanfattning : The global traffic is experiencing an exponential growth posing severe challenges to the communication networks in terms of capacity. As a future-proof technology fiber communication is widely implemented in different network segments, which can be categorized by transmission distance as long-haul and short-reach. LÄS MER
5. Low noise frequency combs and their use in broadly tunable lasers and optical coherence tomography
Sammanfattning : Frequency combs revolutionized the world of laser physics by providing a link between the microwave and optical domains. Such a link allows for precise knowledge of any comb line’s absolute average location, as well as the average spacing between any two comb lines. LÄS MER
