Exceptional points in lossy media enable decay-free wave propagation
Alexander Yulaev, Sangsik Kim, Qing Li +4
Waves entering a spatially uniform lossy medium typically undergo exponential decay, arising from either the energy loss of the Beer-Lambert-Bouguer transmission law or the evanesc…
Milliwatt-threshold visible-telecom optical parametric oscillation using silicon nanophotonics
Xiyuan Lu, Gregory Moille, Anshuman Singh +8
The on-chip creation of coherent light at visible wavelengths is crucial to field-level deployment of spectroscopy and metrology systems. Although on-chip lasers have been implemen…
Broadband Resonator-Waveguide Coupling for Efficient Extraction of Octave Spanning Microcombs
Gregory Moille, Qing Li, Travis C. Briles +7
Frequency combs spanning over an octave have been successfully demonstrated in Kerr nonlinear microresonators on-chip. These micro-combs rely on both engineered dispersion, to enab…
Kerr Microresonator Soliton Frequency Combs at Cryogenic Temperatures
Gregory Moille, Xiyuan Lu, Ashutosh Rao +6
We present measurements of silicon nitride nonlinear microresonators and frequency comb generation at cryogenic temperatures as low as 7~K. The resulting two orders of magnitude re…
Tunable quantum beat of single photons enabled by nonlinear nanophotonics
Qing Li, Anshuman Singh, Xiyuan Lu +5
We demonstrate the tunable quantum beat of single photons through the co-development of core nonlinear nanophotonic technologies for frequency-domain manipulation of quantum states…
Quantum Frequency Conversion of a Quantum Dot Single-Photon Source on a Nanophotonic Chip
Anshuman Singh, Qing Li, Shunfa Liu +10
Single self-assembled InAs/GaAs quantum dots are promising bright sources of indistinguishable photons for quantum information science. However, their distribution in emission wave…
