Light-matter interaction at the transition between cavity and waveguide QED
Daniel Lechner, Riccardo Pennetta, Martin Blaha +3
Experiments based on cavity quantum electrodynamics (QED) are widely used to study the interaction of a light field with a discrete frequency spectrum and emitters. More recently,…
Observation of coherent coupling between super- and subradiant states of an ensemble of cold atoms collectively coupled to a single propagating optical mode
Riccardo Pennetta, Daniel Lechner, Martin Blaha +3
We discuss the evolution of the quantum state of an ensemble of atoms that are coupled via a single propagating optical mode. We theoretically show that the quantum state of N atom…
Collective radiative dynamics of an ensemble of cold atoms coupled to an optical waveguide
Riccardo Pennetta, Martin Blaha, Aisling Johnson +4
We experimentally and theoretically investigate collective radiative effects in an ensemble of cold atoms coupled to a single-mode optical nanofiber. Our analysis unveils the micro…
Broadly tunable photon pair generation in a suspended-core fiber
Jonas Hammer, Maria V. Chekhova, Daniel R. Häupl +2
Nowadays fiber biphoton sources are nearly as popular as crystal-based ones. They offer a single spatial mode and easy integrability into optical networks. However, fiber sources l…
Optomechanical cooling and self-stabilization of a waveguide coupled to a whispering-gallery-mode resonator
Riccardo Pennetta, Shangran Xie, Richard Zeltner +2
Laser cooling of mechanical degrees of freedom is one of the most significant achievements in the field of opto-mechanics. Here, we report, for the first time to the best of our kn…
Flying Particle Microlaser and Temperature Sensor in Hollow-Core Photonic Crystal Fiber
Richard Zeltner, Riccardo Pennetta, Shangran Xie +1
Whispering-gallery mode (WGM) resonators combine small optical mode volumes with narrow resonance linewidths, making them exciting platforms for a variety of applications. Here we…
Broadband, Lensless and Optomechanically Stabilised Coupling into Microfluidic Hollow-Core Photonic Crystal Fiber Using Glass Nanospike
Richard Zeltner, Shangran Xie, Riccardo Pennetta +1
We report a novel technique for launching broadband laser light into liquid-filled hollow-core photonic crystal fiber (HC-PCF). It uniquely offers self-alignment and self-stabiliza…
