Brillouin lasers in Bragg grating microresonators
Ryan L. Russell, Moritz Merklein, Choon Kong Lai +5
Chip-scale coherent light sources are required in applications spanning metrology and sensing to telecommunications. Brillouin lasers (BLs) offer a route to ultra-coherent optical…
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…
Brillouin-based phase shifter in a silicon waveguide
Luke Mckay, Moritz Merklein, Alvaro Casas Bedoya +8
Integrated silicon microwave photonics offers great potential in microwave phase shifter elements, and promises compact and scalable multi-element chips that are free from electrom…
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…
