Resonators with tailored optical path by cascaded-mode conversions
Nature Communications, 2023 Resonators are key components in optics. In this work, the authors introduce a class of optical resonators with distinctly different properties from conventional resonators, allowing fundamental design trade-offs to be circumvented.

Optical Microdiscus Resonators [PDF]
Conference on Lasers and Electro-Optics 2012, 2012 We present a new “soften-and-squash” method for turning microspheres into high quality, stand-alone microdiscus resonators. Due to the annealing involved in the fabrication process, their measured Q factors are one order of magnitude better than the starting microspheres.

High-Q suspended optical resonators in 3C silicon carbide obtained by thermal annealing.
Optics Express, 2020 We fabricate suspended single-mode optical waveguides and ring resonators in 3C silicon carbide (SiC) that operate at telecommunication wavelength, and leverage post-fabrication thermal annealing to minimize optical propagation losses.

First-order perturbation theory for changes in the surrounding of open optical resonators. [PDF]
Optics Letters, 2019 The single-mode approximation of resonant state expansion has proven to give accurate first-order approximations of resonance shifts and linewidth changes when modifying the material properties inside open optical resonators.

Optical Whispering-Gallery-Mode Microbubble Sensors
Micromachines, 2022 Whispering-gallery-mode (WGM) microbubble resonators are ideal optical sensors due to their high quality factor, small mode volume, high optical energy density, and geometry/design/structure (i.e., hollow microfluidic channels).

Direct measurement of coating thermal noise in optical resonators [PDF]
Physical Review D, 2018 The best measurements of space and time currently possible (e.g. gravitational wave detectors and optical reference cavities) rely on optical resonators, and are ultimately limited by thermally induced fluctuations in the reflective coatings which form ...

The missing link between standing- and traveling-wave resonators
Nanophotonics, 2022 Optical resonators are structures that utilize wave interference and feedback to confine light in all three dimensions. Depending on the feedback mechanism, resonators can support either standing- or traveling-wave modes.

Simulation of two-boson bound states using arrays of driven-dissipative coupled linear optical resonators [PDF]
Physical Review A, 2018 We present a strategy based on two-dimensional arrays of coupled linear optical resonators to investigate the two-body physics of interacting bosons in one-dimensional lattices.

Self-tuning optical resonator [PDF]
Optics Letters, 2017 We demonstrate a nonlinear optical resonator that tunes itself onto resonance with an input beam. In a monolithic Fabry-Perot cavity implemented in rubidium-doped periodically-poled potassium titanyl phosphate, an intensity-dependent refractive index produces line-pulling by multiple free-spectral ranges (FSRs).
