Dual-pumped degenerate Kerr oscillator in a silicon nitride microresonator
Yoshitomo Okawachi, Mengjie Yu, Kevin Luke +5
We demonstrate a degenerate parametric oscillator in a silicon-nitride microresonator. We use two frequency-detuned pump waves to perform parametric four-wave mixing and operate in…
Continuous generation of Rubidium vapor in hollow-core photonic band-gap fibers
Prathamesh S. Donvalkar, Sven Ramelow, Stephane Clemmen +1
We demonstrate high optical depths (50+/-5), lasting for hours in Rubidium-filled hollow-core photonic band-gap fibers, which represents a 1000X improvement over operation times pr…
Silicon-Nitride Platform for Narrowband Entangled Photon Generation
Sven Ramelow, Alessandro Farsi, Stéphane Clemmen +4
CMOS-compatible photonic chips are highly desirable for real-world quantum optics devices due to their scalability, robustness, and integration with electronics. Despite impressive…
Tunable Squeezing Using Coupled Ring Resonators on a Silicon Nitride Chip
Avik Dutt, Steven Miller, Kevin Luke +4
We demonstrate continuous tuning of the squeezing level generated in a double-ring optical parametric oscillator by externally controlling the coupling condition using electrically…
Tunable frequency combs based on dual microring resonators
Steven A. Miller, Yoshitomo Okawachi, Sven Ramelow +5
In order to achieve efficient parametric frequency comb generation in microresonators, external control of coupling between the cavity and the bus waveguide is necessary. However,…
