Forty years ago, four groups of researchers independently developed and demonstrated their own versions of the injection laser, launching a technological revolution in the process. Their exciting early research paved the way for the vast array of materials and technologies used in the production of modern semiconductor alloy devices.
High-quality bare nanofibers are a novelty, but the idea of making them actually goes back 40 years to the work of a pioneering group in Britain. Today researchers believe that unclad submicrometer fibers hold promise for applications in a range of areas, including microphotonics and environmental sensing.
In the not-too-distant future, improvements in luminous flux and luminous efficacy are expected to enable use of white-light LEDS in automobile headlights, large-screen LCD backlighting and general home lighting.

We perceive the world in depth as well as in color, but the generation of high-quality three-dimensional (3D) images is still an area that is fraught with challenges for researchers. Now a ray-optics-based technique—integral imaging—shows promise for 3D TV and visualization.
