Optical vortex Brillouin laser
Xinglin Zeng, Philip St. J. Russell, Yang Chen +5
Optical vortices, which have been extensively studied over the last decades, offer an additional degree of freedom useful in many applications, such as optical tweezers and quantum…
Nonreciprocal vortex isolator by stimulated Brillouin scattering in chiral photonic crystal fibre
Xinglin Zeng, Philip St. J. Russell, Christian Wolff +3
Optical non-reciprocity, which breaks the symmetry between forward and backward propagating optical waves, has become vital in photonic systems and enables many key devices, such a…
Picosecond acoustic dynamics in stimulated Brillouin scattering
Johannes Piotrowski, Mikołaj K. Schmidt, Birgit Stiller +2
Recent experiments demonstrating storage of optical pulses in acoustic phonons based on stimulated Brillouin scattering raise a number of questions about the spectral and temporal…
Coherently refreshed acoustic phonons for extended light storage
Birgit Stiller, Moritz Merklein, Christian Wolff +4
Acoustic waves can serve as memory for optical information, however, acoustic phonons in the GHz regime decay on the nanosecond timescale. Usually this is dominated by intrinsic ac…
On-chip broadband non-reciprocal light storage
Moritz Merklein, Birgit Stiller, Khu Vu +3
Breaking the symmetry between forward and backward propagating optical modes is of fundamental scientific interest and enables crucial functionalities, such as isolators, circulato…
Brillouin spectroscopy of a hybrid silicon-chalcogenide waveguide with geometrical variations
Atiyeh Zarifi, Birgit Stiller, Moritz Merklein +10
Recent advances in design and fabrication of photonic-phononic waveguides have enabled stimulated Brillouin scattering (SBS) in silicon-based platforms, such as under-etched silico…
