Riassunto

Passive Components for Dense Optical Integration presents a theoretical and numerical investigation of high index-contrast (HIC) passive components that can serve as building blocks at the end-points and nodes of WDM communications systems. The main characteristic of these structures is their miniature size and their low radiation loss due to the strong light confinement in high index-contrast systems. Thus large scale, high density optical integration may be possible with the associated advantages of increased functionality, compactness and cost.
Passive Components for Dense Optical Integration presents novel devices for filtering, optical interconnections and coupling to fibers. The latter part of the book explores coupling structures that are only a few wavelengths long yet can provide efficient coupling. Also discussed are possible future directions for this technology.
Passive Components for Dense Optical Integration will be of interest to researchers and development engineers in integrated optics and fiber optics. It also provides an excellent supplement to a graduate course in optics.
