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 correlation-based Brillouin sensing: design, experiment and simulation
Atiyeh Zarifi, Birgit Stiller, Moritz Merklein +10
Wavelength-scale SBS waveguides are enabling novel on-chip functionalities. The micro- and nano-scale SBS structures and the complexity of the SBS waveguides require a characteriza…
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…
On-chip multi-stage optical delay based on cascaded Brillouin light storage
Birgit Stiller, Moritz Merklein, Christian Wolff +5
Storing and delaying optical signals plays a crucial role in data centers, phased array antennas, communication and future computing architectures. Here, we show a delay scheme bas…
Crosstalk-free multi-wavelength coherent light storage via Brillouin interaction
Birgit Stiller, Moritz Merklein, Khu Vu +4
Stimulated Brillouin scattering drives a coherent interaction between optical signals and acoustic phonons and this effect can be used for storing optical information in acoustic w…
