Broadband Resonator-Waveguide Coupling for Efficient Extraction of Octave Spanning Microcombs

October 1, 2019
Author(s)
Gregory Moille, Qing Li, Travis Briles, Su P. Yu, Tara E. Drake, Xiyuan Lu, Ashutosh Rao, Daron Westly, Scott Papp, Kartik Srinivasan
Frequency combs spanning over an octave have been successfully demonstrated on-chip in Kerr nonlinear microresonators, thanks to their large effective nonlinearity and ability to support a suitable dispersion profile. Efficient extraction of intracavity

Kerr Microresonator Soliton Frequency Combs at Cryogenic Temperatures

September 27, 2019
Author(s)
Gregory Moille, Xiyuan Lu, Ashutosh Rao, Qing Li, Daron Westly, Leonardo Ranzani, Scott Papp, Mohammad Soltani, Kartik Srinivasan
We present measurements of silicon nitride nonlinear microresonators and frequency comb generation at cryogenic temperatures as low as 7 K. A resulting two orders of magnitude reduction in the thermo-refractive coefficient relative to room-temperature

Efficient telecom-to-visible spectral translation through ultra-low power nonlinear nanophotonics

June 24, 2019
Author(s)
Xiyuan Lu, Gregory Moille, Qing Li, Daron Westly, Anshuman Singh, Ashutosh Rao, Su P. Yu, Travis Briles, Scott Papp, Kartik Srinivasan
The ability to spectrally translate lightwave signals in a compact, low-power platform is at the heart of the promise of nonlinear nanophotonic technologies. For example, a device to connect the telecommunications band with visible and short near-infrared

pyLLE: a Fast and User Friendly Lugiato-Lefever Equation Solver

May 24, 2019
Author(s)
Gregory T. Moille, Qing Li, Xiyuan Lu, Kartik Srinivasan
The Lugiato-Lefever Equation (LLE), first developed to provide a description of spatial dissipative structures in optical systems, has recently made a significant impact in the integrated photonics community, where it has been adopted to help understand

Chip-integrated visible-telecom entangled photon pair source for quantum communication

January 21, 2019
Author(s)
Xiyuan Lu, Qing Li, Daron Westly, Gregory Moille, Anshuman Singh, Vikas Anant, Kartik Srinivasan
Photon pair sources are fundamental blocks for quantum entanglement and quantum communication. Recent studies in silicon photonics have documented promising characteristics for photon pair sources within the telecommunications band, including sub-milliwatt
