Nanophotonic dispersion engineering in tantala-based microresonators with ultralow-loss claddings
Alexa R. Carollo, Atasi Dan, Jizhao Zang +3
Integrated photonics optimized to leverage low loss, nonlinear-optical processes and optoelectronic integration requires robust optical cladding materials and associated fabricatio…
Photonic-Crystal Microresonator Frequency Combs in the O-band
Sarang Yeola, Alexa R. Carollo, Jizhao Zang +1
Photonic-crystal microresonators (PhCRs) are a powerful platform for generating Kerr frequency combs. Because Kerr-soliton dynamics in PhCRs are largely decoupled from the operatin…
Nanophotonic control of collective many-body states in Kerr solitons
Yan Jin, Jizhao Zang, Sarang Yeola +3
Spatially periodic systems of coupled bosons are governed by on-site interactions and tunneling between sites, opening a rich phase space of many-body behavior. Here, we explore na…
Monolithic 3D integration of tantalum pentoxide photonics on arbitrary substrates
Grant M. Brodnik, Grisha Spektor, Lindell M. Williams +6
The photonics landscape encompasses a wide scope of material platforms, each optimized for specific functionalities, yet no platform meets the demands of all current and evolving p…
Amorphous metal oxide mixtures for high-Q integrated nonlinear photonics
Alexa R. Carollo, Atasi Dan, Haixin Liu +3
Choice of material is ubiquitous in integrated photonics to design device properties, whereas changing material composition is much less common. With phase matching as an additiona…
Next-generation soliton frequency combs in photonic-crystal and nanocomposite microresonators
Haixin Liu, Alexa Carollo, Jizhao Zang +1
Microresonator frequency combs offer tremendous opportunity to advance applications in fundamental research and technology by linking the optical and microwave frequency domains. K…
