Saraswati Associates, a San Francisco-based engineering company, announced it has changed its name to SA Photonics. “We believe our new name better reflects our continued emphasis on photonic-based solutions to many of today’s engineering problems, including RF (radio frequency) photonics, high-bandwidth free-space and underwater communications, person-machine interface issues and high-power microwave (HPM) sensing,” said Jim Coward, SA Photonics president. The company's Web site is now www.saphotonics.com.
