NeoPhotonic launches lasers for silicon photonics modules.

1310nm and 1550nm InP lasers target intra-datacentre 100G connections

NeoPhotonics, a manufacturer of components, modules and subsystems for communications networks, has announced 1310nm and 1550nm high power InP lasers and laser arrays for use in 100G silicon photonics-based QSFP28 modules for datacenter applications.

One specific 100G datacenter application uses silicon photonics parallel single-mode architecture, or PSM4, in a high power laser diode array product. NeoPhotonics has partnered with Mellanox Technologies, a silicon photonics company, to develop laser arrays which can be passively flip-chip bonded onto Mellanox's optical engine producing a high volume, low-cost, electronics style assembly for a 100G PSM-4 module.

"We are pleased that NeoPhotonics has opened its unique high power, high yield laser technology to the ecosystem. Several key laser integration and performance features have enabled us to support our customers with a solid and growing portfolio of high performance LinkX 100G modules and cables," said Mehdi Asghari, vice president of silicon photonics, Mellanox Technologies.

"NeoPhotonics was a pioneer in the development and volume production of InP PIC based DFB lasers and particularly in the extension of this technology to arrays. Among other applications, we have shipped several hundred thousand of these lasers over the last decade into demanding DWDM applications," said Tim Jenks chairman and CEO of NeoPhotonics. "We are pleased to announce the new application of this versatile technology for intra-datacenter 100G connections," continued Jenks.
