A novel 2 x 2 polarization-independent optical switch with holographic optical elements is proposed. The switch consists of an electro-optic half-wave plate sandwiched between two pairs of holographic polarization beam splitters. Normally incident input and output couplings of this compact and lightweight device provide better flexibility and easier alignment for system applications.

The research on engineering experiment is a key step in translating technical development to industrial application. Active, optical range imaging sensors collect three-dimensional coordinate data from object surfaces and can be useful in a wide variety of automation applications, including shape acquisition, bin picking, assembly, inspection, gaging, robot navigation, medical diagnosis, and ca...

We present a tunable delay element that is inherently insensitive to free-carrier loss and achieves up to nanosecond delays even when tuned slowly. This will enable electrically tunable buffers on a silicon chip. ©2009 Optical Society of America OCIS codes: (130.3120) Integrated optics devices ; (230.5750) Resonators ;(230.2090) Electro-optical devices

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.

Abstract: Highly-efficient, fabric-wide calibration of balanced control for optical switch fabrics without built-in power-detectors is first realized with fully-automated implementation. This technique co-optimizes thermo-optic and electro-optic phase elements, correcting phase-error and power-imbalance simultaneously for optimized performance.

The essential optical components include a 5 mW polarized laser (HeNe); single mode, polarization preserving optical fiber with couplers; Wollaston prism, birefringent plate; water immersion 20x microscope objective; electro-optic modulator, and polarization analyzer. The interferometric microscope needs to be compact and stiff, a combination that can be achieved with Microbench components (LIN...

We experimentally demonstrate real-time C-band transmissions with up to 29 dB optical budget after 25 km propagation at 20 Gbit/s and 25 Gbit/s. Our solution uses pre-equalization and electro-optical components dedicaded for 10 Gbit/s transmissions.

We use an ultrafast electro-optic dual comb interferometer to perform single-point vibrometry on the submillisecond time scale. As an example, we resolve the vibration of an ultrasound speaker driven at 50 kHz, achieving a sub-nanometer axial resolution through a measurement of the optical phase carrier.

A new microphotonic mm-wave receiver architecture with direct electrical-to-optical conversion is presented. The receiver uses high-Q RF and microphotonic electro-optic resonator components which are operated in simultaneous resonance. Initial results demonstrating modulation of an optical carrier at RF in the mm-wave range are reported .
