摘要： A device includes a resonator having an oscillating portion with dimensions chosen to lead to a desired resonant frequency. A light source is positioned to provide light along the length of the oscillating portion at a specific wave length. A detector detects a change in oscillation of the resonator responsive to the wave pressure produced by the light source heating a gas. The light source is modulated with a frequency the same as the resonant frequency of the resonator.

摘要： Some embodiments relate to an optical microphone according to an example embodiment. The optical microphone includes a semiconducting laser. The semiconducting laser includes a p-n junction within a cavity. The optical microphone further includes an acoustic membrane that receives coherent light emitted from the semiconducting laser and directs reflected light back toward the semiconducting laser. During operation of the optical microphone, the acoustic membrane flexes in response to pressure waves. The phase of the reflected light is dependent upon a distance of the acoustic membrane from the semiconducting laser.

摘要： A method is disclosed for the planarization of a semiconductor device structure by a two stage planarization process which comprises: applying a dielectric layer over a first conductive layer, spin coating an organic layer onto the first dielectric layer, etching the device in a plasma etching process to substantially remove the organic planarization layer, then etching the device in a plasma etching process which etches the exposed dielectric layer to substantially remove all of it, removing the remaining organic planarization layer, followed by the application of a second dielectric layer under bias sputter deposition conditions. The bias sputter deposition fills trenches and eliminates peaks in the remaining first dielectric layer as it builds up the second dielectric layer. The process planarizes the dielectric layer without thickness variations dependent upon conductor layer pattern density.

摘要： Some embodiments are directed to a photoacoustic sensor. The photoacoustic sensor may comprise: a gas cell with an opening; a light source to generate to radiate a sample gas within the gas cell; an optical microphone to detect the sample gas within the gas cell; and a membrane aligned with the opening of the gas cell to permit sample gas to enter the gas cell. The optical microphone includes a semiconducting laser. The semiconducting laser includes a p-n junction within a cavity of the semiconducting laser. The optical microphone further includes a pressure-sensitive membrane that receives coherent light emitted from the semiconducting laser and directs reflected light back toward the semiconducting laser. During operation of the optical microphone, the pressure-sensitive membrane flexes in response to acoustic pressure waves. The phase of the reflected light is dependent upon a distance of the pressure-sensitive membrane from an aperture of the semiconducting laser.

摘要： Systems and methods for optically pumping alkali-metal atoms using Coherence Population Trapping (CPT) resonances are disclosed. An illustrative push-pull optical pumping system for inducing CPT resonances in a resonance cell containing an admixture of alkali-metal atoms and one or more buffer gasses may include a laser assembly adapted to produce alternating orthogonally polarized light, and at least one DC current source adapted to output a constant-intensity carrier current signal for inducing laser emission from the laser assembly at a carrier wavelength of the alkali-metal atoms. An RF modulated signal outputted from an RF modulation source can be rectified, split, and phase-shifted for inducing a time-dependent polarization of the laser light that can be used to enhance CPT resonances. The alternating orthogonally polarized light from the laser assembly can then be used to optically pump the alkali-metal atoms within the vapor cavity, producing a dark state that can be detected with a photodetector or the like.

摘要： A dynamic micro-structured reflector includes a substrate having a generally planar major surface and a plurality of cavities on the planar major surface. Each cavity having at least a first and second sidewalls set at an angle offset from the planar major surface. The first sidewall being a stationary optical face and the second sidewall being a dynamic optical face. The dynamic optical face is deflectable between a first position and a second position. The dynamic optical face in the first position redirects more light back to a light source than the dynamic optical face in the second position. Methods of making a dynamic micro-structured reflector are also disclosed.
