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…
