Telecom out, solar in: photonics gets its green game on aiming at trillion dollar cleantech opportunity
January 27, 2010 Ever since Alexander Graham Bell pronounced that his "photophone" was his most important invention after he proved in 1880 that he could transmit sound on a beam of light, photonics has been instrinsically linked to the telecommunications industry. Thanks to Bell, photonics companies had a great run in the 20th century with fiber optic applications. Yet 21st century photonics entrepreneurs may well owe their success to the advances they can produce in cleantech.
