NeoPhotonics announces general availability of high-power Telcordia-qualified, non-hermetic 1310nm DFB laser arrays for silicon photonics applications

NeoPhotonics Corp of San Jose, CA, USA (a vertically integrated designer and manufacturer of hybrid photonic integrated optoelectronic modules and subsystems for high-speed communications networks) has announced general availability of high-power 1310nm lasers and laser arrays qualified for use with low-cost, non-hermetic packages for 100G silicon-photonics-based QSFP28 modules in data-center applications.

NeoPhotonics is addressing the need for custom high-power and non-hermetic laser sources to provide the light source for silicon-photonics-based transceivers used for 100Gbps connections within the data center. Deployment of such transceivers in industry-standard multi-source agreement formats such as CWDM4, CLR4 and PSM-4, predominantly in a QSFP28 form factor, is now underway. To support the emerging silicon photonics eco-system, NeoPhotonics has developed and qualified (to the Telcordia GR-468-CORE Issue 2 standard) a line of high-power, uncooled lasers and laser arrays for several industry-leading silicon photonics transceiver manufacturers. Each laser provides an efficient and high-power light source designed around a specific implementation of silicon-based high-speed analog and digital electronic devices and related photonic components. The high-power 1310nm CW DFB lasers are qualified to non-hermetic test compliance with Telcordia GR-468-CORE Issue 2, including damp heat testing for powered non-hermetic devices, and are production ready.

“These uncooled, high-power non-hermetic CW DFB lasers and laser arrays are a critical component for any of the emerging 100G, 200G or 400G silicon-photonics-based transceivers developed for data-center switching applications,” says chairman & CEO Tim Jenks. “These new lasers effectively illustrate the wide-ranging applications for our advanced hybrid photonic integration technology by efficiently combining our high-optical-power indium phosphide (InP) laser technology with our partner’s silicon photonics modulator technology to maximize link performance margins,” he adds.

NeoPhotonics laser developments are focused on three specific customer requirements: (1) the need for high optical power output from 40mW to 70mW for both NRZ and PAM-4 modulation; (2) lasers fully qualified and reliable in non-hermetic packages, making it possible to achieve the high volume and low cost necessary for mega-data-center deployments; and (3) custom laser features that help NeoPhotonics customers use automated laser attach and alignment methods to increase volume and further reduce assembly costs.

The new lasers and laser arrays, along with NeoPhotonics’ broad suite of products for line- and client-side 100G and beyond applications, are being displayed in booth #3017 at the Optical Fiber Comminications Conference and Exhibition (OFC 2017) in Los Angeles (21-23 March).
