When Will OLEDs be the Next Big Thing in Lighting?

Stephanie Pruitt 10/08/2014

OLEDs have been gaining in popularity lately, mainly in displays, but also more recently in general lighting. They offer many benefits over traditional and LED lighting, including being a surface emitting light source (as opposed to point emitting), being extremely thin, and having the capability to be flexible and even transparent. OLEDs open the doors to really innovative and creative light forms that were previously not possible with traditional lighting. However, they still have a ways to go in efficacy, lumen output, and price compared to their less expensive inorganic counterparts that are still struggling to really penetrate into the market.

High-End Lighting Markets for Solid State Lighting

Shonika Vijay 09/30/2014

Lighting has always been seen as a commodity market. In fact, most people buy their light bulbs from the same place they buy their milk. It is a price war out there with slim profit margins on lighting products; meanwhile, the market keeps demanding higher quality. The general indoor lighting market mostly consists of the following form factors: downlights, troffers, suspended pendants, track lights, and high bay lights (a detailed market report of general lighting luminaires with these form factors along with all technologies will be released this November). Downlights and troffers make up the majority of the installed luminaire base for all regions. In order to compete for penetration in these installed luminaire bases, LED lighting has had to slash its prices while making sure it can sustain the light output levels of halogens, incandescent, and fluorescent technologies.

Fiber Laser Market Continues to Evolve

Allen Nogee 09/05/2014

I’ve always been a person who has been very interested in the latest technology, and sometimes it’s hard for me to believe how much technology has changed over the years.

Everything from flat screen TVs, DVRs, audio equipment, cables and wiring, computers, tablets, smartphones, and so many others have evolved over the years, and in most ways, the new technology is quicker, smaller, cheaper, and more energy efficient. Today we take all these things for granted, but it wasn’t that long ago that a flat screen TV or a smartphone was a novelty. Today we just can’t even imagine living without these things.

A Win-Win Situation: Cree Announces Investment in Lextar through Private Placement

Martin Shih 09/05/2014

Cree recently announced plans to invest US $83M in Lextar Electronics, one of Taiwan’s major LED manufacturers, in order to acquire 13% of Lextar shares and to enter a supply/royalty agreement. Cree will become Lextar’s second largest shareholder (AUO, Lextar’s parent company, is the biggest shareholder) and obtain one member of BOD. This deal is expected to be done at the end of 2014 and the lock-up period is 3 years, which means Lextar will reserve its capacity for Cree for 3 years.

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.

CLEO 2009--The year of mid-IR

By Tom Hausken
To name one thing that stands out at an industry event may do an injustice to the many others, but mid-infrared is my pick for CLEO 2009. This is a product category that really seems to be gaining traction. From a market perspective, it has a lot going for it: many new and exciting potential applications, and many new technology solutions. Of course, application development takes time, but there are both near-term and long-term apps. A nice place to be these days.

There was a session in the PhAST Market Forum on mid-IR environmental monitoring. There was a plenary presentation by Federico Capasso, now a professor at Harvard, on quantum cascade lasers. Daylight Solutions , Hamamatsu , Alpes Lasers , Maxion Technologies , and AdTech Optics are some of the companies that make quantum cascade lasers or products built around them. There were also companies showing 2 micron fiber lasers, such as Advalue Photonics , IPG Photonics , and Photonics Industries . And there are usual established players that make OPOs and the pumps to drive them, companies that feature coatings, and so on. Some of the companies have even been hiring through the downturn. MIRTHE, the NSF Center on Mid-Infrared Technologies for Health and the Environment headquartered at Princeton, had a booth at CLEO showing off some applications.

Of course, there were also lots of other great new products and conference presentations. Laser Focus World magazine does a great job covering those topics, I'll leave that to them.

The turnout at CLEO wasn't too bad, considering we are going through the biggest economic downturn in decades. Sure, companies cut back in booth size and attendees, but CLEO attendance was only in the lower end of the range of recent years, not drastically different.

CLEO really addresses scientific and R&D applications--you see lots of ultrafast lasers and fancy instrumentation. The markets for those applications are as close to flat as any today. Which is to say, really good.
