A high-sensitivity detection method for optical power fluctuations is demonstrated based on photodetection in reflection of an optical resonator with a specific impedance matching. That resonator is used to reduce the carrier power reflected by the resonator while preserving the power fluctuation sidebands for frequencies above the resonator bandwidth. A sensitivity of 7 x 10(-10) Hz(-1/2) for ...

The quantum-cascade laser can be used as an infrared source for a small portable photoacoustic trace gas detector. The device that we describe uses a quantum-cascade laser without collimating optics mounted inside an acoustic resonator. The laser is positioned in the center of a longitudinal resonator at a pressure antinode and emits radiation along the length of the resonator exciting an axial...

Use of microwave resonator-based sensors is a relatively new approach for the detection of biological reagents. Sensing mechanism is based on the tracking of the resonant frequency on electromagnetic resonator. Resonant frequency depends on structure geometry and material but is also affected by secondary changes in environment. Addition of a reference resonator to suppress these effects is pro...

The following work reports the design, numerical, analytical and simulation characterization of an Aluminum Nitride MEMS resonator. The paper offers a comparison of rectangular plate MEMS resonator (length extensional and width extensional mode shapes) and ring shape MEMS resonator. It also demonstrates the contour Eigen modes of resonators and their equivalent electric circuit model (BVD). Fur...

-We present a photorefractively pumped ring resonator for the formation of self-organized, topology-preserving mappings. The self-imaging ring resonator with saturable gain and loss supports localized cavity modes at arbitrary transverse locations. When the resonator is pumped by two uncorrelated signals, two spatially well separated modes form. Each mode is correlated temporally with one of th...

Nonlinear phenomena occurring in an optical fiber ring resonator featuring ultrahigh Q factor are experimentally studied. The laser is locked onto the resonator, and the optical power induced in the resonator is controlled. The onset of the first stimulated Brillouin scattering wave occurs at an optical input power as low as -9 dBm in these resonators. When the resonator is used as the frequenc...

We calculate the oscillation conditions and the eigenfrequencies for phase-conjugating-resonator-normal-resonator coupled optical systems. With an eye toward applications to interferometry, we choose specific examples for which it is shown that the conditions for oscillation and the eigenfrequencies depend on the normal-resonator path length. The examples include both linear displacement and ro...

We demonstrate the realization of a hybrid solid-state quantum device, in which a semiconductor double quantum dot is dipole coupled to the microwave field of a superconducting coplanar waveguide resonator. The double dot charge stability diagram extracted from measurements of the amplitude and phase of a microwave tone transmitted through the resonator is in good agreement with that obtained f...

This paper reports on two methods of designing narrow-band resonator filters: the modified equivalent circuit model for transversely coupled resonator filters and modified P-matrix model for balanced bridge resonator filters. To raise the accuracy of simulation on the basis of both the models, we use the experimental parameters obtained for the two-resonator structure of the filter being design...

We consider a theoretical model for a nonlinear nanomechanical resonator coupled to a superconducting microwave resonator. The nanomechanical resonator is driven parametrically at twice its resonance frequency, while the superconducting microwave resonator is driven with two tones that differ in frequency by an amount equal to the parametric driving frequency. We show that the semiclassical app...
