    摘要： An integrated laser-based light source that generates an output light beam having a controlled intensity. The light source comprises a light sensor, a laser, a convex beam-splitting surface, and a package that includes a header. The light sensor generates an electrical signal representing an intensity of light energy falling on it, and is mounted on the header. The laser has one and only one light-emitting face from which a light beam is radiated as a radiated light beam. The laser is mounted in the package adjacent the light sensor with the light-emitting face substantially parallel to the light-receiving face of the light sensor. The convex beam-splitting surface reflects a fraction of the radiated light beam towards the light sensor as a reflected light beam, and transmits the remainder of the radiated light beam as the output light beam. The convex beam-splitting surface is supported in the radiated light beam by the package.

The mechanical support includes a first support element and a second support element. The first support element extends at a non-zero angle from the second support element. The printed circuit board includes a first portion and a second portion in contact with the first support element and the second support element, respectively. The optical communications device is mechanically coupled to the first support element of the mechanical support and is electrically connected to the first portion of the printed circuit board. The integrated packaging system preferably provides automatic alignment between the optical communications device and one or both of an optical element and an optical fiber. In this case, the first support element includes a device alignment feature. The device alignment feature and the optical communications device have a defined positional relationship with respect to one another. Alternatively, the system may additionally comprise a cover assembly including a cover comprising a device alignment feature. The cover is mechanically coupled to the first support element in a position at which the device alignment feature and the optical communications device have a predetermined positional relationship with respect to one another.

    摘要： The present invention provides a n-drive surface emitting laser comprised of an active region, a first mirror region having a first conductivity type, a second mirror region having a second opposite conductivity type, the first and second mirror regions being located on opposite sides of the light generation region, a buffer region having a second conductivity type, and a substrate having a first conductivity type. In the preferred embodiment the first conductivity type is n-type, thus the present invention provides a method of forming an n-drive semiconductor laser on an n-type substrate. Contact is made to the p-type mirror region via a tunnel junction formed by degeneratively doping the areas of the substrate region and the buffer region which abut each other. The tunnel junction is reverse biased so that current is injected through the degeneratively doped p-n junction formed by the n+ substrate and the p-type conducting layer.

    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.
