Kotura Launches Single Channel VOA with Submicrosecond Response Time; Market Leader in Silicon Photonics Announces Single Channel VOA Fast Enough to Control Transient Noise in Optical Networks.MONTEREY PARK Monterey Park, city (1990 pop. 60,738), Los Angeles co., S Calif., a growing residential suburb of Los Angeles; inc. 1916. It is a wholesale, retail, and financial services center. , 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 (Variable Optical Attenuator) A device that can incrementally adjust the power of the optical signal passing through it. 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 hoe, usually a flat blade, variously shaped, set in a long wooden handle and used primarily for weeding and for loosening the soil. It was the first distinctly agricultural implement. The earliest hoes were forked sticks. 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 (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. manufacturing techniques, the Ultra VOA 1030 is a single silicon chip packaged with no moving parts. Attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. 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 In communications, techniques used to reduce distortion and compensate for signal loss (attenuation) over long distances. . 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 (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. VOAs and 1000x faster than traditional VOAs. Availability The Kotura Single Channel Ultra VOA 1030 is available for customers to sample now; production quantities will be available in October, 2005. About Kotura, Inc.
