Lasers Evolve to Meet the Demands of Optical Communications
Feb 1, 2012 — Long-distance, high-speed communication depends on lasers to provide the optical power source. But this application is becoming more and more demanding, especially in terms of power consumption, price and bandwidth. With ever-increasing demands on...
Sensor Reveals 1000 Colors Across Land, Sea, Space
Jan 1, 2012 — It can be used underground, underwater and even in space. A versatile new system, it comprises innovative optics that can be used with any spectrometer, can collect more than 1000 colors and is so stable and reliable that it can be used to detect...
Who Has the Conn?
Jan 1, 2012 — The “conn” is the area of the submarine from which the rudder is controlled and where the periscope is located. Fans of sub movies – and any submariners among our readers – know that “Who has the conn?” is never...
“Smart windows” will adjust to the weather outside
Dec 1, 2011 — Home or office windows soon could be made to darken to shield us from a scorching summer sun, then made to switch back to transparent in winter to take advantage of light and heat available from the sun on those shorter days. A team of Korean...
Research at the Nanoscale Boosts Green Photonics
Dec 1, 2011 — Improving the efficiency of thin-film solar cells is a key challenge, and some believe that nanophotonics could be the answer. Nanophotonic structures give us better control over light, enabling us to manipulate it in ways never seen before...
Smart, Self-Healing Fibers Laugh at Danger
Nov 1, 2011 — Light, sturdy fiber optic sensors can help monitor conditions in power plants, on airplane wings, on dams and in other hard-to-reach places. The composition of fiber optic sensors enables them to be placed in areas where traditional point sensors...
Photonics for a Better World
Oct 1, 2011 — I like the sound of that. I think it could be a great tag line for the industry: “Photonics, for a Better World.” In reality, “Photonics for a Better World” is the name of a special pavilion at SPIE Optics & Photonics,...
The Rise of the Service Robot
Oct 1, 2011 — Industrial robots revolutionized manufacturing, and service robots are set to rise up and do the same in such diverse areas as medical care, surveillance and the military – and also in domestic settings, where they could take over chores from...
Metamaterials: Photonic Sleight of Hand
Sep 1, 2011 — Invisibility cloaks, perfect imaging, enhanced photovoltaic light collection, all-optical memories and biosensing are just some of the intriguing applications of metamaterials currently grabbing headlines in scientific journals. The field of...
Self-assembling polymers could enable ultracheap solar panels
Sep 1, 2011 — It is no surprise that many solar developers believe that polymer (plastic) cells that can cover huge areas could help bring us into a new age of renewable energy. Polymer solar cells are much cheaper to produce than conventional silicon types and...
Solar energy use is maturing, with bumps and bright spots
Sep 1, 2011 — Another summer has just about burned itself out here in our corner of the world, and our active pursuit of sunshine has turned passive as the days begin to shorten and temperatures cool. But it seems that around the world, sunshine – in the...
