Tuning the cavity modes of a Fabry-Perot resonator using gold nanoparticles.
نویسندگان
چکیده
We study the interaction between a planar Fabry-Perot microcavity and a single embedded gold nanoparticle. We record spatially resolved white-light transmission spectra and show that the interaction between microcavity and nanoparticle gives rise to a redshift of the cavity modes, in accordance with the Bethe-Schwinger cavity perturbation formula. The spectral tuning of cavity modes by discrete nanoparticles can be exploited for applications such as optical and micromechanical sensing.

We report on optical properties of Fabry-Pérot (FP) resonator based on Si-air one-dimensional photonic crystal (1D PC) with coupled triple-cavity modes (or defects). These defects obtained by infiltration of the air-cavity with the filler of tunable refractive index. The coupled FP resonators design is CMOS compatible and has potential for application in tuning an individual transmission bands ...
متن کاملExperimental observation of cavity formation in composite metamaterials.
In this paper, we investigated one of the promising applications of left-handed metamaterials: composite metamaterial based cavities. Four different cavity structures operating in the microwave regime were constructed, and we observed cavity modes on the transmission spectrum with different quality factors. The effective permittivity and permeability of the CMM structure and cavity structure we...
متن کاملSubwavelength Fabry-Perot resonator: a pair of quantum dots incorporated with gold nanorod
The two apexes of an elongated gold nanorod (GNR) irradiated by a plane wave are shown to be the hotspots at the longitudinal plasmon modes. This phenomenon implies that a pair of quantum dots (QDs) located at these apexes might be excited simultaneously if the excitation band of QDs coincides with one of these modes. Consequently, a coherent emission of the two emitters could happen subsequent...

The structure of longitudinal modes of a passively Q-switched, non-planar unidirectional ring-resonator,with Nd:YAG active medium is described in this article. Two different techniques are used to study the longitudinal mode structure of the laser resonator. At first, the fast-fourier transform technique is applied for analyzing the mode beating of the optical fields by intensity frequency str...
متن کاملOptically tunable Fano resonance in a grating-based Fabry-Perot cavity-coupled microring resonator on a silicon chip.
A grating-based Fabry-Perot (FP) cavity-coupled microring resonator on a silicon chip is reported to demonstrate an all-optically tunable Fano resonance. In the device, an add-drop microring resonator (MRR) is employed, and one of the two bus waveguides is replaced by an FP cavity consisting of two sidewall Bragg gratings. By choosing the parameters of the gratings, the resonant mode of the FP ...
