	Nano-engineering has been around for a long time. For example, silicon CMOS technology has built smaller and smaller transistors and placed more transistors on a chip. Moore’s law shows feature size decreasing over the years and has allowed us to place 10 billion transistors on a chip in 2010 with a bandwidth of 30 GHz. This has resulted in a great reduction in cost. You can buy a computer today for about the same cost as 30 years ago but the functionality has exponentially increased. Tools such as reactive ion etching (RIE) and e-beam lithography have enabled nano-engineering.		Nano-engineering has been around for a long time.

	Integration requires a series of science and technology advances before a product can be made that people will spend money on, e.g. the MP3 player. Since 2000 all the major journals in EE have been covering photonics integration. Many federal funding agencies are trying to move this vision forward.
