Design of All-Optical Subtractors Utilized with Plasmonic Ring Resonators for Optical Computing

open access: yesPhotonics, 2023
In this paper, a novel plasmonic all-optical half-subtractor and full-subtractor are designed for optical computing. The structure of plasmonic subtractors consists of a metal–insulator–metal (MIM) waveguide and rectangular ring resonators covered by a ...

First-order perturbation theory for changes in the surrounding of open optical resonators. [PDF]

open access: yesOptics 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 LC-like resonances in high-index particles [PDF]

open access: yesPhotonics and Nanostructures - Fundamentals and Applications 58, 101212 (2024), 2023
Electric LC resonances, occurring in metallic circuits, govern the motion of free electrons or electric signals. In this paper, optical LC-like resonances in high-index particles (HIPs) or dielectric LC resonances have been studied, which involve bounded electrons and optical fields instead.

Optical Whispering-Gallery-Mode Microbubble Sensors

open access: yesMicromachines, 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]

open access: yesPhysical 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

open access: yesNanophotonics, 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.

Electromagnetically Induced Transparency and Absorption in Directly Coupled Whispering-Gallery Mode Microcavities

open access: yesIEEE Photonics Journal, 2022
Optical interference and the related effects are key elements which could exhibit the properties of both classical and quantum optical systems. Usually, the interference between different optical paths may produce intriguing effects, such as the ...

Optical interface for a hybrid magnon-photon resonator [PDF]

open access: yes, 2021
We study optical detection of magnetic resonance of a ferrimagnetic sphere resonator, which is strongly coupled to a microwave loop gap resonator. Optical fibers are employed for coupling the sphere resonator with light in the telecom band. We find that magnetic resonance can be optically detected in the region of anti-crossing between the loop gap and

Wavelength-Selective Near Unity Absorber Based on Fabry-Pérot Nanoresonators

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021
We proposed and analyzed a planar narrow-band absorber based on a bi-layer metal/dielectric structure. The planar absorber uses the Fabry-Pérot resonance and the inherent loss of the metals, for maximum light absorption in the range of the ...
