Light Enables Tomorrow’s Technologies

Light Enables Tomorrow’s Technologies

By Elizabeth Rogan


OSA does its part to raise public understanding of optics and photonics through educational outreach programs, professional development opportunities, consumer education campaigns, advocacy activities and more. From OSA’s perspective, the importance of light is evident in the groundbreaking research that is published in our peer-reviewed journals and presented at our technical conferences—much of which serves as perfect examples of light as an enabling technology. For instance:

Smartphone Apps: Researchers used a laser to etch a waveguide directly onto a smartphone display—doing this opens the door to embedding apps such as temperature sensors and biomedical monitors into new real estate: the display glass itself.

Space Communications: MIT and NASA recently presented their results from the Lunar Laser Communication Demonstration, showing how they were able to transmit data, via a laser, over the 385,000 km between the moon and Earth at a record-shattering download rate of 622 megabits per second.

Self-Driving Cars: A new LIDAR (“light radar”) system has been developed that can remotely sense objects across distances as long as 30 feet – which could one day enable your self-driving car to spot a child in the street half a block away, let you answer your Smartphone from across the room with a wave of your hand or play “virtual tennis” on your driveway.

Wearable Tech: Google Glass made its mass market debut earlier this year and researchers are working on ways to improve similar augmented reality technology by superimposing 3-D images on the display to reduce strain on the eyes. Meanwhile, a new biometric-sensing wristwatch that uses light to monitor glucose and dehydration levels is the first wearable device that can measure glucose concentration directly and noninvasively.

Urban Lighting: In response to ever-crowded urban conditions in developing countries, researchers in Egypt have developed an inexpensive way of re-directing natural sunlight into dimly lit streets and alleys, where lack of sun is linked to health problems.
Cases like these of how light and light-based technologies can improve our everyday lives are plentiful. OSA is excited to lend its voice and resources to showcase the role of optics and photonics in society on a global scale.

OSA has already kicked off its IYL programs with a Facebook Contest called “What Will You Do for IYL?” Chances are you have an idea or two of how to raise awareness for light – we’re giving away $500 to put the best ideas into action. Join us now and help us spread the word about the importance of light in 2015 and beyond.
