With the rapid growth of the telecom and datacom market, the information throughput in switching and routing systems such as digital cross-connects or IP routers is increasing immensely. This causes the systems to continually move to higher data rates and also to become more decentralized. The result is a huge demand for high-speed interconnects within those systems. We have developed a 4-channel Transceiver link with a data rate of 2.5Gb/s/ch and are able to provide an ideal solution to overcome this data bottleneck.The Transceiver modules incorporate a 1310nm Fabry-Perot laser diode array and a maximum link length of 2km is specified using single-mode fiber. Providing a hermetic seal on the package guarantees highest reliability. The package is also designed for solder reflow used in standard assembly lines. Our Transceiver modules are now ready to be produced in large volume quantities.
The shape of inverted cylindrical magnetrons makes them ideal for coating a variety of optical components having non-planar geometries such as prisms, gratings and spherical lenses. In addition, combining dual cathode mid frequency unbalanced magnetron sputtering with the cylindrical geometry produces a unique source for ion enhanced deposition on planar substrates located at the ends of the cathode. Using a 330 mm diameter source, thickness uniformity on stationary substrates of ± 0.25 % over a diameter of 160 mm and ± 1.3 % over 200 mm can be achieved. SiO 2 and Ta 2 O 5 deposited on Si have indices of refraction at a wavelength 632 nm of 1.47 and 2.13 respectively and dispersion similar to those reported for ion assisted processes. The off-axis nature of this arrangement makes such sources particularly useful where the acceleration of negative ions produced at the target surface can damage sensitive materials such as OLEDs.
