On-the-fly particle metrology in hollow-core photonic crystal fibre
Abhinav Sharma, Shangran Xie, Richard Zeltner +1
Efficient monitoring of airborne particulate matter (PM), especially particles with aerodynamic diameter less than 2.5 um (PM2.5), is crucial for improving public health. Reliable…
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…
Long-range optical trapping and binding of microparticles in hollow-core photonic crystal fibre
Dmitry S. Bykov, Shangran Xie, Richard Zeltner +4
Optically levitated micro- and nanoparticles offer an ideal playground for investigating photon-phonon interactions over macroscopic distances. Here we report the observation of lo…
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…
Polarization-selective out-coupling of whispering gallery modes
Florian Sedlmeir, Matthew R. Foreman, Ulrich Vogl +6
Whispering gallery mode (WGM) resonators are an important building block for linear, nonlinear and quantum optical experiments. In such experiments, independent control of coupling…
High-Q MgF whispering gallery mode resonators for refractometric sensing in aqueous environment
Florian Sedlmeir, Richard Zeltner, Gerd Leuchs +1
We present our experiments on refractometric sensing with ultrahigh-Q, crystalline, birefringent magnesium fluoride (MgF) whispering gallery mode resonators. The difference to…
