Launches single channel VOA with submicrosecond response time
March 1, 2005
MONTEREY PARK, Calif. -- Kotura, Inc. a leading provider of silicon photonic components, today announces the Kotura Ultra Variable Optical Attenuator 1030, a very fast single channel VOA in a compact package. Next week Kotura will be showcasing the product at Booth 2010 at the OFC/NFOEC Conference in Anaheim, Calif.
“When a back hoe cuts an optical fiber, spikes in optical power can create noise or damage other components in the network. VOAs must have a response time of less than a few microseconds to prevent this from happening,” explained Arlon Martin, VP of Sales and Marketing. “Our VOAs solve this problem. In addition they can implement the modulation schemes required for emerging network features like wavelength tracking”.
Kotura’s Silicon Photonics Approach
Built using standard CMOS manufacturing techniques, the Ultra VOA 1030 is a single silicon chip packaged with no moving parts. Attenuation is accomplished by free carrier absorption. Because of the fast response time, the Ultra VOA 1030 is the ideal candidate for transient control and wavelength tracking applications. At the same time, it performs standard VOA functions like power balancing and channel equalization.
Kotura’s existing VOA products, 4 channel and 8 channel Ultra VOA Arrays, have achieved full Telcordia qualification and are in volume manufacture. The new Ultra VOA 1030 expands the product line with a new version for single channel applications. Kotura VOAs are typically 100x faster than MEMS VOAs and 1000x faster than traditional VOAs.
