Reduction of hydroxyl groups in optical nanofibers via in-fiber laser heating
Koki Oguri, Ken-ichi Harada, Samuel K. Ruddell +2
Optical nanofibers fabricated using a standard oxyhydrogen flame exhibit optical losses at wavelengths around 1385~nm due to absorption by embedded hydroxyl groups, posing a challe…
Fabrication of high-Q defect-free optical nanofiber photonic crystal resonators
Tomofumi Tanaka, Takahiro Suzuki, Owen Mao +3
We demonstrate the fabrication of defect-free optical-nanofiber photonic-crystal Fabry-Perot resonators with quality factors exceeding 10^7 using single-shot femtosecond laser abla…
Ultra-low-loss nanofiber Fabry-Pérot cavities optimized for cavity quantum electrodynamics
Samuel K. Ruddell, Karen E. Webb, Mitsuyoshi Takahata +2
We demonstrate the fabrication of ultra-low-loss, all-fiber Fabry-Pérot cavities containing a nanofiber section, optimized for cavity quantum electrodynamics. By continuously monit…
Origins of clustered frequency combs in Kerr microresonators
Noel Lito B. Sayson, Hoan Pham, Karen E. Webb +6
Recent experiments have demonstrated the generation of widely-spaced parametric sidebands that can evolve into "clustered" optical frequency combs in Kerr microresonators. Here we…
Widely tunable optical parametric oscillation in a Kerr microresonator
Noel Lito B. Sayson, Karen E. Webb, Stéphane Coen +2
We report on the first experimental demonstration of widely-tunable parametric sideband generation in a Kerr microresonator. Specifically, by pumping a silica microsphere in the no…
Collective strong coupling of cold atoms to an all-fiber ring cavity
S. K. Ruddell, K. E. Webb, I. Herrera +2
We experimentally demonstrate a ring geometry all-fiber cavity system for cavity quantum electrodynamics with an ensemble of cold atoms. The fiber cavity contains a nanofiber secti…
Experimental observation of coherent cavity soliton frequency combs in silica microspheres
Karen E. Webb, Miro Erkintalo, Stéphane Coen +1
We report on the experimental observation of coherent cavity soliton frequency combs in silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere…
Efficiency of dispersive wave generation from a dual-frequency beat signal
K. E. Webb, M. Erkintalo, Y. Q. Xu +2
The emission of dispersive waves (DWs) by temporal solitons can be described as a cascaded four-wave mixing process triggered by a pair of monochromatic continuous waves (CWs). We…
Measurement of microresonator frequency comb stability by spectral interferometry
Karen E. Webb, Jae K. Jang, Jessienta Anthony +3
We demonstrate a new technique for the experimental measurement of the spectral coherence of microresonator optical frequency combs. Specifically, we use a spectral interference me…
Nonlinear optics of fibre event horizons
Karen E. Webb, Miro Erkintalo, Yiqing Xu +4
The nonlinear interaction of light in an optical fibre can mimic the physics at an event horizon. This analogue arises when a weak probe wave is unable to pass through an intense s…
