To achieve mass adoption, LEDs will require better materials that produce brighter, longer-life devices with improved color rendering. The price of LEDs has come down rapidly over the past three years, and this trend is expected to continue over the next couple of years until LED lamps reach mass adoption cost.

Light Sources, Filters Enable 3-D Sensing Advances
Improving the manufacturability, reliability and size of hardware components for 3-D sensing systems opens up new applications for the technology. As the technology evolves, sensors are detecting ever-finer motions and characteristics. Modern sensors can not only detect a head nod, but also precisely identify to whom the head belongs. Besides identity, they can detect heartbeats and the subtle facial characteristics that communicate emotions. And 3-D sensing has moved outdoors to environments that previously were too bright or had complex lighting that precluded useful surveillance.

Offering energy efficiency and a wide color gamut, the quantum dot could be the next big thing in display technology. After 25 years of research and development, quantum dots – man-made semiconducting crystals so tiny they are invisible to the naked eye – are ready for their close-up.

LEDs, Other Optoelectronic Components Merging for Emerging Applications
A key trend in optoelectronics is the integration of light-based components into single multifunctional building blocks. Although LEDs are quite dominant in the market, the IHS report predicts that optocouplers – especially in gate-driver applications such as hybrid and electric vehicles, photovoltaic inverters and smart meters – will grow from $543 million in 2013 to $677 million in 2018, which represents 25 percent growth in five years.

Physical safeguards, along with software and training, help ensure that embedded lasers rate as Class 1 devices. Hiding your light under a bushel isn’t always a bad thing, contrary to the advice in the old proverb. A case in point can be found in lasers, where low-cost systems are increasingly more powerful – and, therefore, potentially more dangerous.
