Alpine Optoelectronics produces 400G PAM4 nCP4™ SiPho optical engine on tower semiconductor technology

Based on Tower Semiconductor’s market PH18 Silicon Photonics technology platform

Designed for use in 400Gbps DR4 transceivers to support high-speed connectivity in data center applications

Tower Semiconductor the leader in high-value analog semiconductor foundry solutions, and Alpine Optoelectronics, a supplier of high data rate Silicon Photonics optical engine chips, announced that Alpine Optoelectronics, began production of its 400G PAM4 nCP4™ optical engine on Tower Semiconductor’s PH18 Silicon Photonics technology platform. Alpine’s nCP4™ chip converts 4 lanes of 56Gbaud electrical input into 4 lanes of optical output for use in 400Gbps DR4 transceivers to support high-speed connectivity in data center applications.

Alpine selected Tower Semiconductor as a foundry partner 2 years ago, because we believe in Tower’s capabilities of technology development and to seamlessly ramp production,” said Dr. Tongqing Wang, CEO, Alpine Optoelectronics, “We were able to develop a proprietary design to enable wafer level testing and a flexible yet efficient edge coupler that works with both lens coupling and fiber array attachment. We are also pleased with the high OE bandwidth of our modulators, thanks in part to Tower’s selection of PN junction doping.
