We report on a novel, polysilicon surface-micromachined one-dimensional (1-D) analog micromirror array. Large continuous DC scan angle (23.6° optical) and low operating voltage (6V) have been achieved using vertical comb-drive actuators. The actuators and torsion springs are placed underneath the mirror (137 × 120 μm) to achieve high fill-factor (91%). The measured resonant frequency of the mir...

Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image. Coded exposure is a temporal compressed sensing method for high speed video acquisition. In this work, we combine compressive holography and coded exposure techniques and ext...

We demonstrate a 3-D scanning micromirror device that combines 2-D beam scanning with focus control in the same device using micro-electro-mechanical-systems (MEMS) technology. 2-D beam scanning is achieved with a biaxial gimbal structure and focus control is obtained with a deformable mirror membrane surface. The micromirror with 800 micrometer diameter is designed to be sufficiently compact a...

Efficient collection of trapped ion fluorescence is critical for high-fidelity qubit detection and ion-photon logical interconnects in ion trap quantum information processing. The expected size of future many-ion processors place scalability requirements for high efficiency optical collection systems. We report the development and testing of a microfabricated planar ion trap with an integrated ...

We propose an array of submicrometer mirrors to assess luminescent nano-objects. Micromirror arrays (MMAs) are fabricated on Si (001) wafers via selectively doping Ga using the focused ion beam technique to form p-type etch stop regions, subsequent anisotropic chemical etching, and Al deposition. MMAs provide two benefits: reflection of luminescence from nano-objects within MMAs toward the Si (...

We describe an optical switch for use in crossconnects. It is a free-space device, based on multiple bounces in a pair of White cells sharing a spatial light modulator at one end. In a companion paper, we described various polynomial cells, in which the number of outputs was proportional to the number of bounces raised to some power. In the binary device described here, the number of possible o...

Precise knowledge of laser beam parameters is a key requirement in many photonics applications including for lasers and optics used in the transportation industry. This paper reports on a novel motion-free laser beam characterization system using electronically agile digital and analog photonics such as a Digital Micromirror Device (DMD) and an analog variable focal length lens. The proposed sy...

The coded aperture snapshot spectral imaging (CASSI) architecture has been employed widely for capturing hyperspectral video. Despite allowing concurrent capture of hyperspectral video, spatial modulation in CASSI sacrifices image resolution significantly while reconstructing spectral projection via sparse sampling. Several multiview alternatives have been proposed to handle this low spatial re...
