NeoPhotonics is a renowned producer and designer of photonic integrated circuit (PIC) based modules and subsystems for bandwidth-intensive, high speed communications networks.
The company declared that it has accomplished the first phase in its plan, in order to enhance its production capacity of narrow linewidth tunable lasers (NLW-TL). In response to the increasing demand for the NLW-TL product, this initiative was achieved. Following the commencement of the production plan in the Q4 of 2011, the company witnessed two fold increase on its NLW-TL output. Due to the utilization of coherent optical technology combined with industry supply limitation owing to the 2011 flooding in Thailand, the demand for these novel products has exceeded the industry capacity.
The NLW-TLs of NeoPhotonics are widely-tunable, compact, narrow linewidth assemblies with up to 20 mW launch power in the L band and 35 mW in the C band. Narrow linewidths are designed in such a way to promote digital signal processing. The coherent optical transmission utilizes digital signal processing to examine and determine the incoming signal, when integrated with a local oscillator laser in a coherent receiver. Coherent transmission is designed to facilitate carriers to include backbone network capacity cost-effectively. It has the ability to increase the bandwidth of an optical channel from 10 Gbps to 100 Gbps and accommodate the acceleration of wire line and wireless broadband services striking the network.
The NeoPhotonics NLW-TL’s frequency stability and narrow linewidth are supported by a proprietary packaging technology and a phase-shifted DFB laser chip. The laser assembly consists of an electrical and firmware interfaces, in addition to an integrated wavelength locker.
