t seems we are approaching the transmission limits of traditional materials, so those seeking to increase the speed of optics networks are turning to optical interconnects to provide accurate transmission to the next generation of devices, systems and products. In this collection of 12 papers, experts describe their work in vertical cavity surface emitting lasers, the microlens, GRIN lenses, the development of diffractive optics and its future challenges, planar optics, optical buys technology, fiber optics, plastic optical fibers, optical fiber Jisso technology, optical connectors, parallel optical links and optical interconnections in broadband networks.
