The Search for Other Earths
In recent years, astronomers have discovered more than 350 extrasolar planets, or exoplanets. But typical detection techniques are best suited for finding planets that are very dissimilar to Earth in terms of size and orbital characteristics, and it is unlikely that any of these harbor life. So how do astronomers look for planets that could support life? NASA has proposed the Terrestrial...
The road to solar cell supremacy
The silicon traditionally used to make solar panels is costly and inefficient at converting sunlight into electricity, experts say, yet it remains the material most commonly used to make solar...
A closer look at plastic solar cells
Plastic solar cells are lightweight, flexible and, most importantly, cheap to make. But so far, these devices lack one thing: efficiency. Now researchers at the University of Washington in Seattle...
Lasers in solar cell production
Photovoltaic (PV) solar cells have been around for more than 50 years now, enjoying initial commercial success in familiar applications such as powering satellites in space and, later on, digital...
A New World of Fiber Sensors
Optical fiber is well-known for its ability to carry information at high speeds over long distances. Twenty years after the first transatlantic fiber optic cable was laid, these strands of ultrapure...
Getting a foot in the door: The role of photonics in modern security systems
In times past, a guard might demand someone entering his domain to “halt and be identified.” Today that job is increasingly done by security ID systems using a variety of techniques, including...
Taking Semiconductor Manufacturing to the Extreme
As consumer and enterprise demand for faster computers increases, so will the demand for faster computer chips. The speed of computer chips is directly related to the number of transistors that can...
Instant Revenue: Marketing and Mergers

Editorial
Things are looking up
The word from Washington and Wall Street these days is that better days are ahead. From President Obama to Federal Reserve Chairman Ben S. Bernanke to Treasury Secretary Timothy F. Geithner, the message is that we have hit the bottom of the recession and are headed up. All this is good news for the photonics industry. Stimulus funds are pouring into green technologies such as solar power,...

Lasers light a better way to build a sub
By using laser projection instead of paper and string, an estimated half a million dollars could be saved on every Virginia-class submarine hull built by the General Dynamics Electric Boat Div. in Quonset Point, R.I. That adds up to tens of millions of dollars in construction cost savings for the planned fleet of attack submarines. Development of the technique was funded by the Office of Naval...
Guiding light is not just a soap opera
Computers of the future may use light rather than electricity for logic functions. “There is this dream of the all-photonic circuit to guide light and perform functions,” commented Willie Padilla, a...
