Skew-free parallel optical links and their array technology

Parallel optical links are promising key techniques for increasing the transmission capacity and distance of high-throughput interconnections in B-ISDN systems. The most important requirements in these links are small size, low power consumption, and low cost. These requirements cannot be met using the optical devices and modules used in conventional long-haul, large-capacity optical transmission systems. This paper describes some new parallel optical links and their array technologies.
