Integrated Optics Make Inroads
This year, integrated optics will begin to gain a significant foothold in commercial optical circuits, both in telecom and consumer electronics. Two years from now, they will most likely be predominant in optical circuits. Such devices are built by fabricating optical nanostructures on optical wafers that are then diced to create compact, high-performance optical chips. The value of the integrated optics comes in reducing the size and cost and in increasing the functionality of an optical...
