A resonance based micro pressure sensor is designed and simulated an analytical overview of its working presented. The resonator used electrostatically actuated clamped-clamped (cc) beam supported over docks. correlation between stress in micro-resonator width docs the support structure evaluated. It compared to a without it found that with provides better sensitivity. Performance device evalua...

The paper investigates the nonlinear modal interaction of longitudinal and flexural vibrations a beam resonator under periodic thermal loading. mode parametric oscillations is investigated conditions internal multiple resonance between some forms free resonator. possibility longitudinal-bending generation in system has been found, frequency slow envelope which essentially depends on parameter d...

A micro-scale resonator suspended over a substrate and illuminated with a continuous wave (CW) laser forms an interferometer which couples deflection of the resonator to light absorption. In turn, absorption creates temperature and thermal stress fields which feedback into the motion. Experiments have shown that this coupling can lead to limit cycle oscillations in which the resonator vibrates ...

Piezoelectrically excited, resonant, elastic beams find wide use as piezoelectric fans, optical choppers, MEMS sensors, and piezoelectric motors. The devices consist of either one piezoelectric ceramic patch (piezopatch) bonded on one side (asymmetric configuration), or of two oppositely poled patches placed symmetrically on either side of a thin, flexible elastic beam (symmetric configuration)...

High power chemical lasers often have high aspect ratio gain regions, for which an unstable resonator with different magnifications in the two transverse dimensions is desirable. This paper considers a new class of unstable resonators which achieves the differential magnification property with spherical mirrors by suitably tilting the mirrors through large angles. Output optical quality has bee...

In this paper I present an overview of optical parametric oscillator-the basic mechanism and several advantages of it. One application of using OPO as a differential interferometer is explained in detail. The basic mechanism of OPO OPO is short for optical parametric oscillator, which consists essentially of an optical resonator and a nonlinear optical crystal. It is driven by a pump beam and g...

The primary proton beam for the production of the intense antiproton beam required by FAIR will be provided by a dedicated 70 MeV, 35 mA, 325 MHz Injector. This will be the first linac based on coupled H-mode cavities [1]. A half scale model of the coupled CH modules 3 and 4 of the FAIR proton injector has been constructed and tested. Fabrication of a full scale high power cavity is scheduled f...

The far-field intensity distribution (FFID) of a beam generated by a phase-unifying mirror resonator was investigated based on scalar diffraction theory. Attention was paid to the parameters, such as obscuration ratio and reflectivity of the phase-unifying mirror, that determine the FFID. All analyses were limited to the TEM00 fundamental mode.

A novel flattened ring resonator design utilizing Etched Beam Splitters (EBS) in InGaAsP/InP is proposed and demonstrated. A multiple-thickness hard mask that compensates for RIE-lag realizes waveguides and EBS gaps in a single etch step. ©2009 Optical Society of America OCIS codes: 230.5750 Resonators, 250.5300 Photonic integrated circuits
