White-light cavity with competing linear and nonlinear dispersions
نویسندگان
چکیده
We experimentally demonstrate that broad, tunable bandwidth of an optical ring cavity can be achieved by making use of the negative dispersion of the Kerr nonlinear refractive index in the three-level electromagnetically-induced transparency medium. For a given cavity field intensity, the white-light cavity condition can always be satisfied by choosing the appropriate coupling beam parameters. This white-light cavity scheme can be used effectively to achieve large buildup intensity in the signal-recycling cavity with a broad bandwidth in future advanced gravitational wave detectors.

Cavity linewidth narrowing and broadening due to competing linear and nonlinear dispersions.
We experimentally demonstrate cavity linewidth control by manipulating dispersion of the intracavity medium. By making use of the dramatic change of Kerr nonlinearity near electromagnetically induced transparency resonance in a three-level atomic system, the cavity transmission linewidth can be greatly modified. As the cavity input intensity increases, the cavity linewidth changes from below to...
متن کاملPreparation of Ultra Dispersive Glasses for Designing Novel Coatings
In order to attain glasses with ultra dispersions properties, different heavy metal oxides were used. The desired glasses were obtained from the addition of high amounts of PbO and Bi2O3 to B2O3 based glasses. Refractive index measurements were carried out accurately at different wavelengths by the minimum angle of deviation in prisms method employing a spectrometer. Results indicated that, as ...
متن کاملThe quantum-optical Josephson interferometer
The photon-blockade effect, where nonlinearities at the single-photon level alter the quantum statistics of light emitted from a cavity1, has been observed in cavity quantum electrodynamics experiments with atomic2,3 and solid-state systems4–8. Motivated by the success of single-cavity quantum electrodynamics experiments, the focus has recently shifted to the exploration of the rich physics pro...
متن کاملBand Structures for 2D Photonic Crystals in Presence of Nonlinear Kerr Effect Calculated by Use of Nonlinear Finite Difference Time Domain (NFDTD) Method
We report the simulation results for impact of nonlinear Kerr effect on band structures of a two dimensional photonic crystal (2D-PhC) with no defect, a PhC based W1-waveguide (W1W), and also Coupled-Cavity Waveguides (CCWs). All PhC structres are assumed to a square lattice of constant a made of GaAs rods of radius r=0.2a, in an air background. The numerical simulation was performed using...

We investigate harvesting electrical energy from Gaussian white, Gaussian colored, telegraph and random phase-random amplitude (RARP) noises, using linear and nonlinear electromechanical systems. We show that the output power of the linear system with one or two degrees of freedom, is maximum for the Gaussian white noise. The response of the system with two degrees of freedom is widened in a la...
