Aspects of the subject technology relate to a shaker module for an electronic device. The shaker module may include a movable component that is resiliently suspended in relation to a voice coil by one or more gap-separated pairs of the flat springs. The flat springs reduce the z-height of the shaker module for implementation in, for example, compact electronic devices. The gap-separated pairs of flat springs facilitate adjustment of the resonance frequency of the shaker module substantially independently of adjustments to drop performance, while providing stability against unwanted rocking motions of the movable component.

Shaker for electronic device

A beam modulator () for modulating a beam () includes a modulator element () and a housing assembly (). The modulator element () is positioned in the path of the beam (). The housing assembly () retains the modulator element (). Additionally, the housing assembly () defines a resonant cavity () with the modulator element () positioned therein. The housing assembly () includes a size adjuster () that can be moved to selectively adjust the size of the resonant cavity (). As a result thereof, in certain embodiments, the resonant frequency of the beam modulator () can be easily tuned over a relatively large frequency range.

Electro-optic modulator with adjustable cavity size

A beam modulator () for modulating a beam () includes a modulator element () and a housing assembly (). The modulator element () is positioned in the path of the beam (). The housing assembly () retains the modulator element (). The housing assembly () can include a housing (), a first retainer assembly (), and a second retainer assembly (). The first retainer assembly () flexibly secures the modulator element () to the housing () and the second retainer assembly () fixedly secures the modulator element () to the housing () with the modulator element () positioned between the retainer assemblies () (). With this design, the retainer assemblies () () can cooperate to retain the modulator element () in a fashion that applies a substantially uniform and small pressure across the modulator element ().

Electro-optic modulator

An optical interleaver for use in a range of telecommunications applications including optical multiplexers/demultiplexers and optical routers. The optical device includes an optical processing loop which allows multi-stage performance characteristics to be achieved with a single physical filtration stage. Optical processing on the first leg and second legs of the loop is asymmetrical thereby improving the integrity of the optical signals by effecting complementary chromatic dispersion on the first and second legs. A fundamental filter cell within the interleaver filters optical signals propagating on each of the two legs of the optical loop which intersects the fundamental filter cell.

Optical interleaver and filter cell design with enhanced clear aperture

An isolator is disclosed that features a single birefringent correction element. The correction element is configured to eliminate differential group delay and walk-off simultaneously.

Optical isolator with reduced insertion loss and minimized polarization mode dispersion

The present invention is a hybrid cell that utilizes a PBS pair in conjunction with a wedge tuner and a crystal to achieve a more stable interleaver. A first PBS splits an incoming optical signal into two orthogonally polarized beams which follow different optical paths through the cell. The length of the wedge tuner and crystal are selected such that the periodicity of the cell is approximately inversely proportional to the free spectral range at a target frequency. The length of the wedge tuner and crystal are also selected such that there is no change in an optical path difference between the two optical paths with respect to a change in temperature over an operating temperature range.
