NeoPhotonics doubles capacity of narrow-linewidth tunable lasers for coherent DWDM systems

NeoPhotonics Corp of San Jose, CA, a vertically integrated designer and manufacturer of photonic integrated circuit (PIC)-based modules and subsystems for bandwidth-intensive, high-speed communications networks, says that it is in the process of doubling capacity for the production of narrow-linewidth tunable lasers, with minimal expected additional capital expenditures. The firm offers these lasers in an OIF multi-source agreement (MSA) standard ITLA (integrable tunable laser assembly) form factor, and they are designed to provide the low noise and narrow linewidths required for 40 and 100Gbps coherent applications.

The products are compact, widely tunable laser assemblies designed to be optimized for narrow linewidth with launch powers of up to 35mW in the C band and 20mW in the L band. The narrow linewidth and frequency stability are enabled by a NeoPhotonics phase-shifted DFB (distributed feedback) laser chip and proprietary packaging technology, while the ITLA assembly also includes an integrated wavelength locker as well as industry-standard electrical and firmware interfaces. The narrow-linewidth tunable laser has been available to customers since April 2010 and has become one of the leading lasers used in coherent systems, the firm claims.

“Our narrow linewidth tunable lasers are key components for coherent transport in telecommunications systems, which we believe is rapidly emerging as a dominate architecture for 40 and 100Gbps networks,” says CEO Tim Jenks. “We believe there is currently a shortage of these critical products while demand continues to grow.” The extra capacity is expected to come on-line in first-quarter 2012.
