摘要:
A ferrule for an optical fiber connector having open fiber clamping grooves. The ferrule has a body having a plurality of open grooves for clamping the terminating end sections of optical fibers. At least a section of the longitudinal opening of the groove is provided with opposing lips to provide a clamping effect. The width of the longitudinal opening defined between the lips along at least a section of the grooves is narrower than the diameter of the optical fibers to create a tight fit. The grooves and the width of the longitudinal groove openings are shaped and sized to retain the fibers without any clearance to allow for movement of the fiber relative to the groove. Similar grooves may be provided in the ferrule body for alignment guide pins. The grooves are precision formed by high throughput processes, such as stamping and extrusion.

Polymer substrates, in particular polyimide substrates, and polymer laminates for optical applications are described. Polyimide substrates are polished to an average surface roughness of about 0.25 &mgr;inch, and single-layer or multi-layer waveguide structures are deposited on the polished polyimide substrates. Laminates including polymer or a hybrid organic/inorganic waveguiding film can be deposited on a polished polyimide substrate. The laminate can also include ceramic, piezoelectric and metallic layers. Optical waveguide devices are machined by laser ablation using a combination of IR and UV lasers. A waveguide-fiber coupler with a laser-machined groove for holding the fiber is also disclosed.

An apparatus includes a substrate having at least one opening through a top surface to a bottom surface, the substrate also having a first plurality of aligned grooves formed in the top surface and a plurality of fibers, where each of the plurality of fibers are positioned over the opening and in contact with the substrate within a corresponding one of the first plurality of grooves. In another aspect, a method of manipulating fibers includes placing a plurality of fibers on a substrate to extend over an opening formed through a top surface of the substrate to a bottom surface of the substrate, and flowing air through the opening to draw the plurality of fibers down towards the top surface of the substrate, and positioning each of said plurality of fibers in substantial alignment.

The present invention relates to a positioning system for automatically positioning and attaching at least one optical fiber inserted into said positioning system along a predetermined optical axis. This positioning system comprises a base member with a flat upper surface and a V-shaped reception channel which is parallel to the upper surface and is formed therein for receiving at least one optical fiber. This system also includes a spring-effect retaining member which is mounted on the upper surface of the base member for maintaining the at least one optical fiber inserted into the reception channel. This invention provides for a simple structure, as well as, for a precise and mechanically resistant coupling since the retaining member comprises a membrane which is parallel to the upper surface of the base member, which is mounted above the reception channel and which can be resiliently diverted in a direction perpendicular to the upper surface of said base member. When the at least one optical fiber is inserted into the reception channel, the membrane is diverted so as to fix said optical fiber in the reception channel due to the restoring force of the membrane.

An optical device, and a method of producing the device, are disclosed. The device comprises a substrate and an optical waveguide component affixed to the z, substrate with a glass frit fusion seal formed and locked within a recessed void in the substrate, the glass frit fusion seal being the fused product of a low melting glass frit. The recessed void in the substrate includes a region for receiving the optical waveguide component and an intersecting region that secures the placement of the glass frit fusion seal. The optical waveguide component is affixed to the substrate in order to control temperature varying optical properties of the component.
摘要:
A connection process between an optical fiber and an optical microguide, the microguide having on a substrate, a structure having two media and a core between the media and whose refractive index is higher than those of the media, wherein substantially anisotropic etching takes place of the structure from one end of the microguide, so as to eliminate from the structure a zone allowing the axis of the core as the median line and whose width is at least equal to the external diameter of the fiber. Etching by a dry process takes place of part of the substrate which is located beneath the thus eliminated zone and over a depth making it possible to bring into coincidence the core of the microguide and the core of the fiber, when the latter rests on the bottom of the recess formed in this manner in the substrate and the fiber is fixed in said recess.
