STEM Programs Struggle to Satisfy the ‘Endless Demand’ for Photonics Talent
Earlier this year, at a major recruitment event at the University of Arizona’s Wyant College of Optical Sciences (OSC), the job openings listed outnumbered students in attendance. This imbalance exemplifies the immense pressure STEM programs...

Consumer AR/VR Headsets Focus on Nontraditional Optics
The promise of commercial augmen-ted and virtual reality (AR/VR) technologies seems always to be just around the corner. Nearly three decades have passed since the Sega Corporation announced its Sega VR gaming headset, which was one of the first of...

A High-Resolution View of the Universe
Under ideal circumstances, the resolution of an optical system is limited by the diffraction of light waves. This diffraction limit, the maximum resolution a telescope can achieve, improves linearly with the telescope’s aperture. However, the...

Great Strides in Optical Fabrication
In 2018, a six-and-a-half-meter mirror made up of 18 hexagonal segments will quietly unfurl 1.5 million km from Earth, marking the end of years of intense research and refining of optics fabrication techniques. In the silence of space, the James...

Optics, Photonics Programs Are Lighting the Way
While schools nationwide are welcoming students for the start of the new academic year, we profile three of the country’s top university optics and photonics programs — oldest to newest — that are shaping the future of the...

Displays You Wear
Challenges still exist in the development of wearable devices, but continued advances may ultimately change how people interact with the world around them. It’s a case of a sight for sore eyes and other body parts, with display advances...

Big Photonics Advances Build and Power Big Telescopes
Bigger aspheric mirrors enable astronomers to see farther into space – but they require special designs. For astronomers, bigger is better: In general, the scientific value of a telescope scales to the fourth power of its diameter. So,...

Aspheres Deal with Bigger Deviations
New tools and the integration of measurement capabilities into design software are helping to solve problems – and scientists in academic and government laboratories are researching tomorrow’s solutions. Aspheres are increasingly used...

+-Co-Doped Phosphate Waveguides
Researchers investigate the principle of loss cancellation in proposing a configuration of lossless microring filters fabricated on Er3+/Yb3+-co-doped phosphate glass and using ion-exchanged techniques. The optical round-trip length and the coupling...

Photonics in Space
What would we know about the universe without the aid of optics? A whole lot less than we do now, to be sure. Optics has always played a significant role in both manned and unmanned space missions, while astronomical study would be largely...
Photonics Spectra, December 2010
Seeing Better to Shoot Better
With better eyes in the sky and on the ground, soldiers soon will see the battlefield more clearly than ever. Thanks to sensor innovations, screen improvements, faster digital processing and other advances, military imaging systems will capture and...
Photonics Spectra, April 2010
Twisting the light away
Reducing the size of spectroscopic biosensors by integrating waveguides into microchannel systems is generally a good idea, but it is limited because the beam from the light source typically intersects with the analyte at a relatively small window....
