These problems can be solved using bottom-up nanowires grown by vapor–liquid–solid mechanism, in which lattice strain is elastically relieved at the nearby surface. Examples of high-quality interfaces between heavily mismatch materials exist when both materials are from the same semiconductor group ...
The basic OADM architecture is based on a power splitter, which generates two replicas of the signals, one for the drop and one for the channels that will continue through the nodes. A channel blocker prevents those channels that have been selected to be dropped from continuing to the OADM ...
where each network node is attached to its nearby neighboring nodes (typically two to four links fan out per node). The links in a backbone network vary in length with the distribution of the network nodes or cities, and can vary from tens to hundreds of kilometers. In the latter case,...
Such effects might include the effects of wind on a suspended cable, “stick-slip” phenomena combined with expansion and contraction during temperature changes, vibration from nearby equipment, or traffic or construction near a buried cable, and so on. U.S. Pat. No. 7,173,690 (Haran) ...
Ideally, each optical switch 90 is formed from a luminescent material 36 activated by a different frequency of IR light than that of nearby optical switches 90. Therefore, a corresponding frequency laser diode 92 is used to activate the luminescent material 36 in each optical switch 90, allowing...
21 and 22 as being concave it may be alternatively be of planar configuration in which case the second beam waist is at the nearby mirror 25 rather than within the crystal 35. Amplifying mirrors of the sort illustrated in FIG. 13 can also have polarization dependence. In a further ...
The coupler typically includes a beam splitter for simultaneous direct and television viewing. A camera relay tube is also normally used to keep the camera (which cannot be sterilized) as far from the sterile field as possible. Even if it is possible to insert the endoscope into the patient...
1B, the electrical modulation signal is provided by an RF voltage source 50 having a single signal line 52 and a ground line 54, both embodied by a RF waveguide such as a coaxial cable. The signal line 52 of the driver 50 is connected to the signal transmission line conductor S of ...
When the diseased tissue is removed from this site a nearby fiber will be selected and the process repeated. The same type of computer control should be feasible with many other detection schemes. Multiple fibers connected to individual diodes, or to a vidicon or imaging detector, can be ...
The details of the connection between the edge router 60 and the typically nearby core router may be varied. A conceptually simple design relies on multi-wavelength fiber transmission of super packets between the core router and the edge router 60, that is, the link between the edge and core...
