Vernier Microcombs for Integrated Optical Atomic Clocks
Kaiyi Wu, Nathan P. O'Malley, Saleha Fatema +8
CMOS-compatible Kerr microcombs have drawn substantial interest as mass-manufacturable, compact alternatives to bulk frequency combs. This could enable deployment of many comb-reli…
Architecture for Integrated RF Photonic Downconversion of Electronic Signals
Nathan P. O'Malley, Keith A. Mckinzie, Mohammed S. Alshaykh +5
Electronic analog to digital converters (ADCs) are running up against the well-known bit depth vs bandwidth tradeoff. Towards this end, RF photonic-enhanced ADCs have been the subj…
Switching dynamics of dark-pulse Kerr comb states in optical microresonators
Elham Nazemosadat, Attila Fülöp, Óskar B. Helgason +7
Dissipative Kerr solitons are localized structures that exist in optical microresonators. They lead to the formation of microcombs --- chip-scale frequency combs that could facilit…
High-order coherent communications using mode-locked dark-pulse Kerr combs from microresonators
Attila Fülöp, Mikael Mazur, Abel Lorences-Riesgo +7
Microresonator frequency combs harness the nonlinear Kerr effect in an integrated optical cavity to generate a multitude of phase-locked frequency lines. The line spacing can reach…
Dark breathers in a normal dispersion optical microresonator
Chengying Bao, Yi Xuan, Daniel E. Leaird +2
Breathers are localized waves, that are periodic in time or space. The concept of breathers is useful for describing many physical systems including granular lattices, Bose-Einstei…
Long-haul coherent communications using microresonator-based frequency combs
Attila Fülöp, Mikael Mazur, Abel Lorences-Riesgo +8
Microresonator-based frequency combs are strong contenders as light sources for wavelength-division multiplexing (WDM). Recent demonstrations have shown the potential of microreson…
