Photonik II. Teilvorhaben: Photonische Baugruppen fuer optische mehrfachparallele Verbindungen Abschlussbericht

Parallel optical links are considered to be a favorable solution to overcome the growing bottle-necks of electrical connections for short distances and high transmission capacity per time and area, e.g. for the application fields datacom and exchange networks. A key function for realizing the required low cost solutions adapted to mass market demands is attributed to array components and respective packaging concepts and techniques. These issues, considering both single mode and multimode fiber systems, including fabrication relevant conditions, were therefore core tasks in the project. A major successful achievement was the development of vertical cavity laser arrays (VCSEL) of high uniformity and reliability, for low cost multimode fiber systems, with 850 nm transmission wavelength, temperature range from 0 to 85 C, 12 channels in parallel with data rates up to 1.25 Gbit/s for each channel. For single mode fiber systems at 1300 nm the development work was aimed at edge emitting laser arrays, microlens arrays and a packaging scheme with precision etched silicon submounts for transmitter and receiver modules. The project results establish a favorable basis for introducing optical parallel multimode fiber links to mass markets. For single mode fiber systems, the array technology is still not mature enough to show the anticipated advantages in respect to performance, simplification of production and cost reduction.
