Soliton Microcomb Generation in a III-V Photonic Crystal Cavity
Alberto Nardi, Alisa Davydova, Nikolai Kuznetsov +5
Photonic crystals, material structures in which the dielectric function varies periodically in one, two, or three dimensions, can provide exquisite control over the propagation and…
Ultrafast tunable lasers using lithium niobate integrated photonics
Viacheslav Snigirev, Annina Riedhauser, Grigory Lihachev +13
Recent advances in the processing of thin-film LNOI have enabled low-loss photonic integrated circuits, modulators with improved half-wave voltage, electro-optic frequency combs an…
A heterogeneously integrated lithium niobate-on-silicon nitride photonic platform
Mikhail Churaev, Rui Ning Wang, Viacheslav Snigirev +12
The availability of thin-film lithium niobate on insulator (LNOI) and advances in processing have led to the emergence of fully integrated LiNbO3 electro-optic devices, including l…
Microwave-to-optical conversion with a gallium phosphide photonic crystal cavity
Simon Hönl, Youri Popoff, Daniele Caimi +3
Electrically actuated optomechanical resonators provide a route to quantum-coherent, bidirectional conversion of microwave and optical photons. Such devices could enable optical in…
Optomechanics with one-dimensional gallium phosphide photonic crystal cavities
Katharina Schneider, Yannick Baumgartner, Simon Hönl +5
Gallium phosphide offers an attractive combination of a high refractive index ( for vacuum wavelengths up to 4 μm) and a wide electronic bandgap (2.26 eV), enabling optical ca…
Strong optomechanical coupling in a slotted photonic crystal nanobeam cavity with an ultrahigh quality factor-to-mode volume ratio
Katharina Schneider, Paul Seidler
We describe the design, fabrication, and characterization of a one-dimensional silicon photonic crystal cavity in which a central slot is used to enhance the overlap between highly…
