For the first time the use of a porous microresonator placed in a microelectrofluidic system for integrated functions of nanofiltration and sensing of small biomolecules and chemical analytes in extremely dilute solution was proposed and investigated. As an example, aminoglycosides in drug residues in food and livestock products were considered as the trace chemical analyte. The filtration proc...

In order to study the interacting quantum gases of lithium atoms, we have developed a novel dipole trap based on the resonant enhancement of a far detuned standing wave in an optical resonator. Light from an ultrastable 2-W Nd:YAG laser is coupled into the resonator and enhanced 130-fold, thus creating a trap depth of ~1 mK for the lithium atoms. It enables us to trap ~10-10 laser-cooled atoms ...

We design a polarization-sensitive resonator for use in mid-infrared photodetectors, utilizing a photonic crystal cavity and a single or double-metal plasmonic waveguide to achieve enhanced detector efficiency due to superior optical confinement within the active region. As the cavity is highly frequency and polarization-sensitive, this resonator structure could be used in chip-based infrared s...

We demonstrate an integrated nanophotonic network in diamond, consisting of a ring resonator coupled to an optical waveguide with grating in- and outcouplers. Using a nitrogen-vacancy color center embedded inside the ring resonator as a source of photons, single photon generation and routing at room temperature is observed. Furthermore, we observe a large overall photon extraction efficiency (1...

In this paper an all-optical switch has been proposed based on photonic crystal T-type ring resonator. The finite different time domain (FDTD) and plane wave extended (PWE) methods are used to analyze the behavior of the structure. The T-type ring resonator has a low switching time of about 0.95ps and low switching power equal to 156mW/μm 2 . Since the structure has a simple geometric shape wit...

We demonstrate a 1x2 all-optical comb switch using a 200 mum diameter silicon ring resonator with a switching time of less than 1 ns. The switch overcomes the small bandwidth of the traditional ring resonator, and works for wavelength division multiplexing applications. The device has a footprint of ~0.04 mm(2) and enables switching of a large number (~40) of wavelength channels spaced by ~0.85...

Fast resonance frequency modulation of a superconducting stripline resonator is investigated. The experiments are performed using a novel device which integrates a hot electron detector (HED) into a superconducting stripline ring resonator. Frequency modulation is demonstrated by both applying dc current or voltage to the HED, and by applying optical illumination, with modulation frequencies of...

A regenerative amplifier free-electron laser (RAFEL) is a highgain resonator FEL which achieves saturation in a few round-trips of the radiation in a high-loss, and hence low feedback, optical cavity. Because the radiation feedback fraction is low it is feasible that the use of low reflectivity optics in the resonator makes the RAFEL a candidate for short wavelength operation [1]. Several RAFEL...

We show a diffraction-based coupling scheme that allows a micro-resonator to directly manipulate a free-space optical beam at normal incidence. We demonstrate a high-Q micro-gear resonator with a 1.57-um radius whose vertical transmission and reflection change 40% over a wavelength range of only 0.3 nm. Without the need to be attached to a waveguide, a dense 2D array of such resonators can be i...
