Abstract:
One or more cavities are formed in the bonding surfaces of one, all, or some of the elements to be bonded. These cavities serve as receptacles for the bonding material and are where the bonds are localized. The cavities are of sufficient size and shape so that their volume is greater than the volume of bonding material forming the bond. This ensures that when the elements are brought into contact with one another to mate, the bonding material, which can flow prior to solidifying into a bond, will flow into the cavities and will not impede the separation of the parts. This allows the parts to be mated with nominally zero separation. Once solidified, the bonding material forms a localized bond inside each cavity. Different cavity shapes, such as, rectangular, circular, or any other shape that can be injected or filled with adhesive material may be used.
Abstract:
A circular mirror (12) is connected to the gimble (44) at opposing, but offset from center axis locations (36) and (37) and by compound longitudinal hinges (40) and (42).
Abstract:
A system for controlling a purely photonic network comprising: at least one digital computing device configured for: storing instructions which, when executed by one or more processors, cause the instructions to control a photonic network, the photonic network comprising purely photonic elements that require no electrical-to-optical or optical-to-electrical conversion between a network input port and a network output port, wherein the digital computing device stores: 1) relationship information that describes the relationships between a plurality of network elements in the photonic network; and 2) configuration information that describes the current state of each of the plurality of network elements; receiving a path generation request that includes a first port identifier and a second port identifier, wherein the first port identifier represents an input port and the second port identifier represents a first output port; based at least in part on the relationship information and the configuration information, generating candidate paths that begin at the input port and end at at least the first output port.
Abstract:
A method for generating optical paths in a photonic network is provided. A model of a photonic network is used to store relationship information that describes the relationships between photonic network elements, as well as configuration information about the elements of the photonic network. A path manager receives a request to generate one or more paths based on an input port and one or more output ports. Using the information stored in the photonic network model, the path manager generates one or more candidate paths.
Abstract:
Apparatus and methods are provided for driving a two-axis “X-Y” MEMS mirror using three (1, 2, 3) non-contact actuation elements or electrodes. A differential bi-directional mirror control uses unipolar drive voltages biased at a suitable value. Transformation functions map two-axis tip tilt commands to three actuation drive signals for selected electrode orientations and sizes.
