NeoPhotonics targets DFB lasers at 100-Gbps silicon photonics designs

Optical component and module vendor NeoPhotonics Corp. (NYSE: NPTN) has unveiled 1310-nm and 1550-nm high-power lasers and laser arrays for silicon-photonics-based QSFP28 modules.

The uncooled lasers and arrays should find use in optical transceivers for data center applications, the company says. This includes optical modules based on a variety of multi-source agreements (MSAs), including CWDM4, CLR4, and PSM-4. Each of these MSAs call for indium phosphide direct feedback (DFB) laser, NeoPhotonics points out.

The lasers support power from 40-60 mW over a wide temperature range, the company adds.

NeoPhotonics says it has joined with Mellanox Technologies to develop laser arrays that can be passively flip-chip bonded onto Mellanox's optical engine. The result is a high-volume, low-cost, electronics-style assembly for a 100G PSM4 module.

"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-data center 100G connections."
