A packaged optical micro-mechanical device. A die includes one or more optical micro-mechanical devices on a first surface of a substrate. The first surface includes a die reference surface. A package frame includes an aperture and a package frame reference surface proximate the aperture adapted to receive the die reference surface such that the optical micro-mechanical devices are located in the aperture. One or more V-grooves are positioned relative to an optical interface reference plane adjacent to the micro-mechanical devices and terminating adjacent to the aperture. One or more optical fibers are located in the V-grooves optically coupled with one or more of the optical micro-mechanical devices.

337/036000

A micrometer sized, single-stage, vertical thermal actuator with controlled bending capable of repeatable and rapid movement of a micrometer-sized optical device off the surface of a substrate. The vertical thermal actuator is constructed on a surface of a substrate. At least one hot arm has a first end anchored to the surface and a free end located above the surface. A cold arm has a first end anchored to the surface and a free end. The cold arm is located above the hot arm relative to the surface. The cold arm is adapted to provide controlled bending near the first end thereof. A member mechanically and electrically couples the free ends of the hot and cold arms such that the actuator bends generally at the flexure so that the member moves away from the substrate when current is applied to at least the hot arm.

A member mechanically and electrically couples the free ends of the hot and cold arms such that the member moves away from the substrate when current is applied to at least the hot arm. The hot arm can optionally include a grounding tab to minimize thermal expansion of the cold arm.

525270

A solvent-free hot melt process, for preparing a non-thermosettable, pressure-sensitive adhesive from a tackified non-thermoplastic hydrocarbon elastomer. The process employs a continuous compounding device that has a sequence of alternating conveying and processing zones. The processing zones masticate and mix materials in them. Non-thermoplastic elastomers having high molecular weight may be readily compounded into adhesives in the process.
