Many biological systems possess confined structures, which produce novel influences on the dynamics. Here, stochastic resonance (SR) in a triple cavity that consists of three units and is subjected to noise, periodic force vertical constance studied, by calculating spectral amplification η numerically. Meanwhile, SR given differences from other structures are explored. First, it found parameter...

We demonstrate a single-mode Brillouin fiber ring laser, which is passively stabilized at pump resonance frequency by using self-injection locking of semiconductor pump laser. Resonance condition for Stokes radiation is achieved by length fitting of Brillouin laser cavity. The laser generate singlefrequency Stokes wave with linewidth less than 0.5 kHz using approximately 17-m length cavity.

in this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled inas/gaas quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. the microcavity wafer sample is grown by molecular beam epitaxy (mbe) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

A plasmonic waveguide coupled system that uses a metal-insulator-metal (MIM) waveguide with two silver baffles and a coupled ring cavity is proposed in this study. The transmission properties of the plasmonic system were investigated using the finite element method. The simulation results show a Fano profile in the transmission spectrum, which was caused by the interaction of the broadband reso...

We present a newly developed microwave resonant cavity for use in optically detected magnetic resonance (ODMR) experiments. The cylindrical quasi-TE(011) mode cavity is designed to fit in a 1 in. magnet bore to allow the sample to be optically accessed and to have an adjustable resonant frequency between 8.5 and 12 GHz. The cavity uses cylinders of high dielectric material, so-called "dielectri...

Introduction The majority of RF coils are formed from inductive lengths of copper in various geometries, which are tuned to resonance by incorporation of appropriate capacitors. Volume coils are based on geometries which have a (co)-sinusoidal variation in azimuthal current distribution to produce a homogeneous transverse RF field [1]. An alternative approach is to design a cavity resonator, in...
