Octagonal toroid microcavity for mechanically robust optical coupling

open access: yesAIP Advances, 2015
Light is usually coupled to a whispering gallery mode cavity using a tapered fiber. However, it is difficult to stabilize the optical coupling against mechanical vibration because it requires sub-μm control of the gap distance between the fiber and ...

Experimental and Computational Investigation of an “Open” Transonic Cavity Flow [PDF]

open access: yes, 2009
This paper presents an investigation of a transonic flow (M∞ = 0.85) over a rectangular cavity having a length-to-depth ratio of 5. Velocities were measured inside the cavity on the central plane and two off-centre planes using a two-component particle ...

Evaporation‐driven octagonal particle deposition on the patterned substrate

open access: yesDroplet, 2022
Understanding noncircular deposition patterns can offer broad applications; however, the phenomena have not been thoroughly studied. We experimentally investigate particle self‐assembly of microspherical polystyrene particle‐laden sessile droplets dried ...

Plasmonic sensor for rapid detection of water adulteration in honey and quantitative measurement of lactose concentration in solution

open access: yesResults in Physics, 2023
In this article, a novel surface plasmon polariton-based plasmonic refractive index sensor is proposed and numerically investigated. It consists of a structure of an octagonal cavity resonator inside a square disk along with silver nanodots and two slits

Self-pulsing dynamics in a cavity soliton laser [PDF]

open access: yes, 2010
The dynamics of a broad-area vertical-cavity surface-emitting laser (VCSEL) with frequency-selective feedback supporting bistable spatial solitons is analyzed experimentally and theoretically. The transient dynamics of a switch-on of a soliton induced by

Cavity QED with Multilevel Atoms [PDF]

open access: yes, 2005
The steady-state transmission spectrum of a cavity with two modes of orthogonal polarization strongly coupled to a single atom with multiple Zeeman states is computed. Effects due to cavity birefringence and atomic ac-Stark shifts are included.
