摘要： A flexible printed circuit board (FPCB) for fiber optic modules includes a board with multiple bends, forming a structure with sides and a bottom. The traces in the FPCB traverse from the opto-electronic chips, through the sides of the FPCB, to the module interconnects at the bottom. The multi-fold structure allows the FPCB to support a higher number of traces than conventional single-fold FPCB's, and it allows the fanning out of signal traces from the opto-electronic and electronic chips at the front of the fiber-optic module, thereby reducing the crosstalk between the traces. This higher number is provided with a FPCB that features a single insulating layer and without the need to criss-cross the traces, resulting in improved signal integrity over conventional multi-layer FPCB's.

摘要： An orthogonal electrical connector using a ball edge array includes one or more stackable fiber optic transceivers, wherein each transceiver includes an electrical substrate, and arrays of solder, which is in form of solder balls or solder paste. The solder is held in predetermined position adjacent to the electrical traces on both sides of the electrical substrate inserted into voids on the molded housing and aligned to contact the electrical traces on the motherboard. The electrical traces on the electrical substrate and the motherboard are located close enough so that the solder physically touches both parts during the soldering process. The solder is reflowed by heat, and the melted solder “wicks up” the electrical traces on the electrical substrate by surface tension.

The flexible circuit may be composed of a polymer material. The optoelectronic device is positioned on the substrate such that the optoelectronic device is located within an opening in the subassembly body. The opening may become an enclosed cavity when the optical element is attached to the subassembly body.

摘要： An optical fiber faceplate transmits light signals between an optical fiber communications device and optical fibers secured by a fiber optic connector. The optical fiber faceplate includes a plurality of closely spaced optical fiber segments which prevent light signals from diverging as they pass through the faceplate. The diameters of the cores of the optical fiber segments within the faceplate are smaller than the diameters of the optical fibers secured by the fiber optic connector. Therefore, light from optical signals communicated by the optical fibers is received and transmitted through the faceplate via a plurality of optical fiber segments within the faceplate. Consequently, the faceplate does not need to be precisely aligned with either the optical fibers or the optical communications device.

摘要： A VCSEL that is adapted to the fabrication of an array of VCSELs. A VCSEL array according to the present invention includes first and second VCSELs for generating light of a predetermined wavelength. Each VCSEL includes a bottom reflector comprising an epitaxial layer of a semiconductor of a first conductivity type, a light generation region and a top reflector comprising a semiconductor of a second conductivity type. A bottom electrode is electrically connected to the bottom reflector, and a top electrode is electrically connected to the top reflector. The bottom electrode is grown on top of a buffer layer having an electrical conductivity less than a predetermined value and a crystalline structure that permits epitaxial growth of the bottom reflector on the buffer layer. The buffer layer may be grown on top of a substrate or be the substrate itself in the case in which a substrate having sufficiently low conductivity is utilized. The bottom reflector of each of the VCSELs is in contact with the top of the buffer layer. The first and second VCSELs are electrically isolated from one another by a trench extending into the buffer layer. The buffer layer is constructed from a material having resistivity that is sufficiently low to prevent cross-talk between the first and second VCSELs.

摘要： A connector housing for a connector to an optical device includes: a body with a bottom wall, a first side wall with a first lip, a second side wall with a second lip, where optical fibers may reside within the bottom, first side, and second side walls, where the first and second lips engage the optical fibers when residing within the bottom, first, and second side walls, where the first and second lips assist in preventing the optical fibers from being removed from the body; a spring coupled to the body and the optical fibers; and a sleeve coupled to the body, including a locking feature for locking the body to the optical device. The connector housing is compact in size, allowing larger numbers of fiber-optic modules to reside on a printed circuit board, increasing its density for optical devices. A connector with the connector housing is also more cost effective to manufacture.

摘要： A modular fiber-optic transceiver has an optoelectronic subassembly stack assembled in the beam direction and parallel to the plane of the mounting site. The subassembly is formed in various combinations of individually designed building modules for aligning, focusing, optoelectronic processing and eventual cooling. The subassembly is electrically conductive connected to a transceiver board and kept in perpendicular orientation to it by a snap fitting housing. The housing holds the cable plug of the fiber cable in position and transmits thereby the peripheral imposed mechanical load directly onto the mounting site. The modular building concept supports various techniques for fiber optic data transmission.
