摘要： An optical switch includes a substrate having therein optical waveguides made of silicon and a silicon layer deposited on its top surface. A space is formed in the crossing portion of the optical waveguides which is covered with a lid, preferably made of low alkali borosilicate glass, and which is bonded to the silicon layer by anodic bonding. Preferably, a groove is formed in a surface of the optical waveguide substrate or a bonding surface of the lid. The groove, after the lid has been bonded, makes a passage which communicates between the space and an outside. The passage is a pouring slit for pouring an index-matching liquid and is connected to the space which acts as a driving slit in which the index-matching liquid moves. In one embodiment, the width of the pouring slit is smaller than that of the driving slit. The optical switch can be manufactured by providing an optical waveguide substrate and a lid substrate, one of which is formed with a groove in its surface on which the two substrates are bonded. The optical waveguide substrate and the lid substrate are bonded together by anodic bonding to make a passage which communicates between the space formed in a crossing portion of the optical waveguides and an outside. The regulation of the volume of the index-matching liquid is time-, temperature-, or pressure-based regulation.

摘要： A mechanically stable self-aligned M.times.N optical switch having a low insertion loss is achieved by employing three cleaved silica optical structures containing a plurality of waveguides. A monolithic silica optical structure is cleaved into the three corresponding structures. Each of the first and third structures has a cleaved edge and a respective set of waveguides extending parallel to a corresponding structure surface. The second structure has two substantially parallel cleaved edges and a plurality of sets of waveguides extending parallel to a corresponding structure surface. The corresponding surfaces of the first, second and third structures are positioned on, for example, surfaces of respective first, second and third bases aligned in a common plane. The structures are further positioned with the cleaved edges of the second structure arranged adjacent to and facing respective ones of the cleaved edges of the first and third structures. In operation, the second structure is moveable in a direction along the cleaved edges relative to the first and third structures to selectively align different waveguide sets with the waveguides of the first and third structures to provide various different optical connections between the waveguide sets of the first and third structures.

摘要： A method of manufacturing an optical waveguide device. The method involves removing a portion of an upper cladding layer 110 from above a waveguide 106 and depositing a temporary spacer layer 114 in place of the removed upper cladding 110. A metal membrane 116 is deposited and patterned over the temporary spacer layer 114 and the temporary spacer 114 is removed, leaving the metal membrane 116 suspended over the waveguide 106. When a voltage differential is applied between the metal membrane 116 and electrodes 108 formed on a lower cladding 102, the metal membrane 116 is collapsed against the waveguide 106, attenuating any light transmitted by the waveguide 106.

摘要： A switching element defines a transmitting state and a reflecting state for a pair of intersecting waveguides that have a gap at their intersection. In the preferred embodiment, the switching element exhibits total internal reflection at the gap sidewall from one waveguide to the other when not in the transmitting state. In the transmitting state, index-matching liquid fills the gap, enabling light to continue in the original waveguide direction. The switching element may use ink jet techniques or bubble techniques to displace index-matching liquid. The index-matching fluid may be projected from a gap between the waveguides by a jet mechanism, or a vapor or dissolved gas bubble may be formed to fill the gap between the waveguides to provide the reflecting state for the switching element. Using either of the techniques, heaters are employed to initiate the switching operation. In some embodiments, more than one heater is utilized. In the preferred embodiment, waveguides are formed on one substrate and heaters are formed on another. Then the substrates are aligned and bonded together to position the heaters in very close proximity to the intersection between the waveguides. Preferably, the switching element is one element in a matrix of such elements for routing signals between arrays of input and output waveguides.

摘要： The imaging system has a photonic circuit chip that includes multiple cores that each includes a port through which an outgoing optical signal exits the photonic circuit chip. Each of the cores is configured such that the outgoing signal exits the photonic circuit chip traveling toward a location that is above or below the photonic circuit chip. Additionally, each of the cores is configured to combine light from one of the outgoing signals with a reference signal so as to generate a signal beating at a beat frequency. The imaging system also includes electronics that use the beat frequencies from the cores to calculate data that indicates a radial velocity and/or distance between the system and one or more objects located outside of the system.

摘要： Wavelength division multiplexing (WDM) has enabled telecommunication service providers to provide multiple independent multi-gigabit channels on one optical fiber. To meet demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost monolithic optical circuit technologies and microelectromechanical systems (MEMS) have become increasingly important. However, further integration via microoptoelectromechanical systems (MOEMS) of monolithically integrated optical waveguides upon a MEMS provide further integration opportunities and functionality options. Such MOEMS may include MOEMS mirrors and optical waveguides capable of deflection under electronic control. In contrast to MEMS devices where the MEMS is simply used to switch between two positions the state of MOEMS becomes important in all transition positions. Improvements to the design and implementation of such MOEMS mirrors, deformable MOEMS waveguides, and optical waveguide technologies supporting MOEMS devices are presented where monolithically integrated optical waveguides are directly supported, moved and/or deformed by a MEMS.
