Winning entry to the 2011 IEEE Photonics Society image search contest

The picture is the winning entry to the 2011 IEEE Photonics Society image search contest. It shows red laser light propagating in a spiral structure fabricated with ultra-low-loss planar waveguide technology. The waveguide technology, which is the result of a collaboration with LioniX BV, allows for propagation loss lower than 0.1 dB/m. This world record low propagation loss allows UCSB to meet the high performance demands of many free space or optical fiber-based photonic applications with integration on a silicon chip. The picture will be published along with an article in the December 2011 IEEE Photonics Society Newsletter.
