Lasers in Medical Imaging: The Forecast Looks Very Bright

Allen Nogee 07/11/2014

Almost all medical imaging to date has used one of three technologies: X-rays, magnetism (MRI), or ultrasound. X-rays alone have been used for almost 120 years now, and although today’s imaging technology has improved vastly over the many years, the fact remains that x-rays, ultrasound, and magnetism are all technologies that, due to many factors, produce coarse images, at least by today’s standards. But what if a very coherent light source was used instead, maybe a laser?

Actually, Optical Coherence Tomography (OCT), which produces images based on the reflections of coherent light, is not a new technology. OCT has been used since the early 1990s, especially in the area of ophthalmology, where the images produced by OCT are 100 times finer than standard images produced by ultrasound. In just the last five years, OCT has become one of the most important retinal imaging techniques used today.

The Impact of the Epistar Acquisition on the LED Industry

Martin Shih 07/09/2014

Epistar (2448.TW) announced a plan to fully acquire Forepi (3061.TW), the second-largest chipmaker in Taiwan, through a share swap (1:3.448), implying 18% share dilution to Epistar. The effective date will be the end of 2014, and Forepi will be delisted from the TAIEX.

After the merger, Epistar will become the world’s largest LED chip maker in terms of capacity with a global market share of 15%, which will better position the company to lead in future technology development.

EPA's New Emissions Cutting Plan Could Have an Effect on LED Lighting

Philip Smallwood 06/30/2014

On June 2nd, the Environmental Protection Agency (EPA) proposed a rule designed to cut carbon dioxide emissions from existing coal plants by as much as 30 percent by 2030, compared with 2005 levels. The EPA will finalize the proposal in mid-2015 and then give states a year to design their own plans to meet targets. The organization will let states meet emission targets for power plants in several ways, including through plant upgrades, by switching from coal to natural gas, by improving energy efficiency, or by promoting renewable energy outside the plant site. This approach will give states greater flexibility in designing plans to meet the EPA’s targets.

Where's the Glare?

Shonika Vijay 06/13/2014

LIGHTFAIR, the world’s largest annual architectural and commercial lighting trade show and conference, took place in Las Vegas last week. I wanted to share my thoughts on what I saw that was of the most interest. The 3 main things I saw were: a lot of LED luminaires, more use of optics in products, and lighting controls being present in nearly every booth. To read up more on controls, please see our blogs: Let's Talk Controls and Lightfair International Gets Smart. I will focus on what I saw in terms of optics and LED luminaires.

Lightfair International Gets Smart

Stephanie Pruitt 06/10/2014

At Lightfair International 2013, it seemed only a handful of companies had a booth with a smart lighting solution - Philips, TCP, and Samsung were among the more recognizable ones that I noticed. Fast forward one year and it seems that smart lighting could be found at almost every booth; even the non-name brand booths seemed to have some sort of solution. Whether this was wireless controls to dim lights or change color through your smart phone - or even gesture control...

    Big money for photonics in data centers

    March 16, 2012 1:44 PM by Tom Hausken
    The best news that photonics people could hear came last week at OFC when Cisco announced that it was buying Lightwire for $271million in cash. Lightwire is a start-up making integrated photonics , and Cisco is interested in it for making interconnects in data centers, among other things. I try not to get intoxicated with financial ups and downs that ultimately benefit only a few investors (if that),and I'm not fond of buzzwords like "integrated photonics," but this is good news for anyone with a similar technology.


    It makes sense that Cisco needs the expertise developed in Lightwire. Companies have spent millions on this; for Cisco to do it itself would take millions more and years of delays. Meanwhile, its competitors--Huawei for one--are encroaching on Cisco's market with technology of its own. Cisco can't rely on the merchant market for everything.


    The data center bottleneck is particularly important. I attended four discussions on the topic, including the OIDA workshop to develop a roadmap (where I was a moderator and am writing the report). The challenge is for the industry to develop new architectures and inexpensive components that can address the many-to-many interconnects necessary in modern data centers, such as those of Google and Facebook. Traditional data centers are not a challenge: a conventional switching hierarchy can store and retrieve data, and that scales predictably. The new data centers don't scale as well.


    Both Google and Facebook made the rounds at OFC, and both claim that the technology is available today, it just has to be commercialized. They say there needs to be a whole new sector of components that don't need to meet Telcordia and NEBS standards. It just has to be good enough for the controlled data center environment. Oh, and make it really really cheap, thank you.


    The one problem I have will all of this is that the net margins for Google and Facebook are about 25% or so. That's net profit, not gross. The optical components suppliers' net margins are a few percent to negative. So how about giving some of that nice margin back to the components suppliers? Especially as many suppliers don't see the return on this new segment justifying the risk.


    That's why Cisco's acquisition is such good news. It's a return for the start-up's investors, but it also means that Cisco is willing to fork over some real money for components.


    The OIDA roadmap report on data center interconnects will be coming out sometime in the coming weeks. Look for it at the OIDA web site or here .

    Good news and not-so-good news in LEDs

    March 2, 2012 7:13 PM by Tom Hausken
    There was good news and some not-so-good news at our 13th SIL event in February. First the good news: it was another record year for LEDs, and for that matter, for the Strategies in Light event. As my colleague, Ella Shum, reported: sales totaled $12.5 billion in 2011, thanks to growth in all major segments except backlights.

    The not-so-good news is that growth will continue through 2012 but the market will be tepid for a few years beyond that, ending in 2016 in about the same place, the way things are going. This is because LED suppliers are so successful in reducing the selling price while improving the performance. Growth in sales is countered by reduction in the LED count (per product) and falling prices, making a double whammy. This is good for increasing penetration of LEDs into lighting and other applications, but it’s hard on suppliers’ profits. In fact, it was a bloodbath, in Ella's words, due to overcapacity.

    Looking at this another way, the LED business is maturing. It still has a long way to go with lighting, of course, and even backlights. But the business is now of such a size that it is starting to behave like DRAMs, to use a cliché. Penetration into new applications is not enough to guarantee LED industry growth through the coming lull. From now on, LED sales will be highly dependent on the fortunes of the end-product markets for backlights, just as DRAM sales are highly dependent on personal computer sales.

    To improve margins and market share, LED suppliers will have to stay ahead in scale and performance. LED lighting, in particular, will require larger volumes and high performance devices. Suppliers that can manufacture well in volume (improving yield and tightening binning, for example) will fare well. The suppliers that cannot may be relegated to older segments that don’t require the performance that lighting does. Or they may simply get squeezed out of the market.
