Nonlinear and Quantum Optics with Whispering Gallery Resonators Revisited

Dmitry V. Strekalov, Nicholas J. Lambert, Christoph Marquardt +5

In 2016 we published a review paper "Nonlinear and Quantum Optics with Whispering Gallery Resonators" (1). While writing this review, we found it often necessary to defer addressin…

Removal of guided acoustic wave Brillouin scattering to the quantum-noise limit using symmetric interferometry in twisted photonic crystal fibers

Vishal Choudhury, Kevin Jaksch, Markus Lippl +3

Guided acoustic wave Brillouin scattering (GAWBS) is a major obstacle in fiber-based quantum and high-speed classical communication systems as well as in interferometry. The transv…

Narrowband Frequency-Entangled Photon Source for Hong-Ou-Mandel Interferometry

Yen-Ju Chen, Sheng-Hsuan Huang, Thomas Dirmeier +5

Hong-Ou-Mandel (HOM) interferometry with entangled photons exhibits distinctive quantum features. By introducing frequency entanglement (discrete-color entangled states) into HOM i…

Indistinguishable MHz-narrow heralded photon pairs from a whispering gallery resonator

Sheng-Hsuan Huang, Thomas Dirmeier, Golnoush Shafiee +5

Hong-Ou-Mandel interference plays a vital role in many quantum optical applications where indistinguishability of two photons is important. Such photon pairs are commonly generated…
