Santur selects Kotura’s silicon photonics multiplexer for 100Gb/s PLC platform

Kotura Inc of Monterey Park, CA, USA, which has been producing application-specific silicon photonics components for communications, computing, sensing, and detection for more than four years, has been selected by Santur Corp of Fremont, CA, a vertically integrated manufacturer of indium phosphide-based tunable lasers for metro and long-haul wavelength division multiplexed (WDM) systems, as a partner in its 100Gb/s platform.

Using a silicon photonics chip, Kotura’s 10-channel optical multiplexers combine multiple 10Gb/s channels onto a single fiber output, reducing the packaging complexity by an order of magnitude.

“Santur required a strategic partner for planar lightwave circuits (PLCs) who could meet our aggressive market entry requirements. Kotura had the team and the technology to deliver on schedule,” says Santur’s president & CEO Paul Meissner. Kotura is an active participant in the IEEE 802.3ba 40Gb/s and 100Gb/s Ethernet Task Force, the Video Electronics Standards Association (VESA) and the Silicon Photonics Alliance (the first formal Community of Interest within the Optoelectronics Industry Development Association). “We wanted to be the first company in the world to deliver 100Gb/s for client connectivity. Kotura played an essential role in our being first to market,” he adds.

“Whereas traditional solutions rely on hundreds of discrete components and a dozen fibers, our integration in a small silicon photonics chip is a critical factor that reduces the assembly complexity and decreases the power consumption,” says Kotura’s president & CEO Jean-Louis Malinge.

The 100Gb/s market is coming much faster than many originally thought, believes Arlon Martin, Kotura’s VP of sales & marketing. “To support high-bandwidth video demand, servers are migrating from 1Gb/s ports to 10Gb/s ports. This is creating a bandwidth bottleneck at the next level of interconnect, driving networking and data center companies to implement their 100Gb/s cards now in order to solve this problem,” he adds.
