Directional coupling of light in nanophotonic circuits has recently attracted increasing interest, with numerous experimental realizations based on broken rotational or mirror symmetries of the light-matter system. The most prominent underlying effec

In this work, we present a packaged whispering gallery mode (WGM) device based on an optical nanoantenna as the coupler and a glass microsphere as the resonator. The microspheres were fabricated from either SiO2 fiber or Er3+-doped fiber, the latter

Interactions between laser beams and plasma are widely studied, mostly with short pulses [1] . Here, we use an experimental setup where the most important instrument is a CW whispering-gallery mode micro-cavity with plasma inside. As one can see in f

We propose and experimentally demonstrate an alternative WGR coupling scheme that is easy to make, requires little alignment, and is both convenient and stable with no need for phase matching. It relies on cavity enhanced Rayleigh scattering. This is
Nanofibre-based optical cavities are particularly useful for quantum optics application, such as the development of integrated single-photon sources, and for studying fundamental light-matter interactions in cavity quantum electrodynamics (cQED). Alt

We present a method for making microbubble whispering gallery resonators (WGRs) from tellurite, which is a soft glass, using a CO2 laser. The customized fabrication process permits us to process glasses with low melting points into microbubbles with

The particular properties of hollow whispering gallery resonators should lead to the advancement of bio- and chemical sensing applications. In this talk, we report on the fabrication of, and mode propagation in, hollow, thin-walled microcavities, kno

Optical microresonators have widespread application at the frontiers of nanophotonic technology, driven by their ability to confine light to the nanoscale and enhance light-matter interactions. Microresonators form the heart of a new method for singl

Sensing with whispering gallery resonators (WGRs) is largely limited by the weak perturbation of the whispering gallery mode (WGM) via the evanescent field. A new sensing regime using quasi-droplet WGMs allows WGRs to move beyond the limitation of th

Cavity input-output relations (CIORs) describe a universal formalism relating each of the far-field amplitudes outside the cavity to the internal cavity fields. Conventionally, they are derived based on a weak-scattering approximation. In this contex
