Nonlinear optical resonance The drive to develop ultrasmall and ultrafast electronic devices using a single atomic layer of semiconductors, such as transition metal dichalcogenides, has received a significant boost. Researchers with Berkeley Lab have recorded the first observations of a strong nonlinear optical resonance along the edges of a single layer of molybdenum disulfide. The existence ... » read more

Photon glue Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials and this effect could harness the most useful characteristics from each material for hybrid solar cells and high efficiency lighting, among other applications. To this end, researchers at the University of Michigan and Queens Coll... » read more

Semiconductor Engineering sat down with Sumit DasGupta, Si2; Simon Bloch, Samsung; Jim Hogan; Mike Gianfagna, vice president of marketing at eSilicon (VP of corporate marketing at Atrenta when this roundtable was held). What follows are excerpts of that discussion. SE: The future of technology isn’t just about technology. It’s about people and regulations, as well. Where are the hurdles ... » read more

Is There Light At The End Of Moore’s Tunnel?
By Brian Bailey - 18 Dec, 2013 - Comments: 2

Last month’s article, “Is There Light At The End Of Moore’s Tunnel,” examined the state of the industry in terms of integrating photonics components onto silicon. It concentrated on the piece that has been the hardest to achieve – the laser. However, as realizing that integration goal has become closer to reality, it has also waned in terms of the number of people who believe it is th... » read more

Is There Light At The End Of Moore’s Tunnel
By Brian Bailey - 22 Nov, 2013 - Comments: 2

Electrons are slow, clumsy and quite easily distracted. They’re slow because it now takes a signal longer to cross a chip than the period of the clock signal. They often don’t travel in straight lines as they collide with other atoms. And electromagnetic interference between adjacent signals can mess with the information they are transferring. On the other hand, light has none of these p... » read more

Manufacturing Bits: Oct. 29

Diamond chips The optical transistor, which transports photons, holds great promise. Photons are not only faster than electrons, but they have less crosstalk. But optical transistors are also expensive and difficult to produce. In a possible breakthrough, the ICFO-Institute of Photonic Sciences has demonstrated a “nano-size” diamond that can act as an efficient optical switch. Researche... » read more

Stanford Photonics In 2013
By Marc David Levenson - 17 Oct, 2013 - Comments: 0

Every September, the Stanford Photonics Research Center and their partners at Scottish Universities and in industry showcase the latest developments in laser applications at an on-campus symposium in Palo Alto, Calif. This year, highlights included remarkable developments in particle accelerators, pollution detection and bio-medicine and looked toward increased societal impact through the Ameri... » read more

Möbius strip ties liquid crystal in knots By tying knots in liquid crystals using a miniature Möbius strip made from silica particles, University of Warwick researchers hope to understand how their intricate configurations and unique properties can be harnessed in the next generation of advanced materials and photonic devices. Given that liquid crystal is an essential material in modern l... » read more

Optical interconnect for flexible electronics
By Michael Watts - 23 Feb, 2013 - Comments: 0

By Michael P.C. Watts At Photonics West, Dow Corning and IBM disclosed a photo-patternable optical interconnect materials set that can support 25 cm interconnect lengths, can be part of a flexible PCB, and survive the industry standard “Telcordia” environmental stress test. The idea of optical interconnect has been circulating as soon as it was realized that chip to chip communication... » read more

SOI Highlights at Common Platform Tech Forum
By Various Writers - 19 Feb, 2013 - Comments: 0

Posted by Adele Hars, Editor-in-Chief, Advanced Substrate News ~  ~ The 2013 Common Platform Technology Forum showcased “the latest technological advances being delivered to the world’s leading electronics companies,” so of course SOI-based topics were well-represented. Happily, those of us who weren’t able to get over to Silicon Valley were able to attend “virtually” via a ... » read more
