Denmark Co-packaged Photonics SFP
Denmark hosts a growing ecosystem for co-packaged photonics SFP solutions, with key players like Coherent, SENKO Advanced Components, and local silicon photonics firms driving innovation and integration.
Co-Packaged Optics (CPO) Overview
Co-packaged optics (CPO) is a disruptive technology designed to increase bandwidth density and energy efficiency by integrating photonics and electronics closely, reducing electrical interconnect lengths, and minimizing power loss and signal distortion at high frequencies (>1.6T) (ASMPT) . In CPO systems, SFP modules can be used as external laser sources (ELSFP), where the laser is placed externally while modulation occurs on the co-packaged photonic IC, isolating heat from the core and maintaining high-speed performance .
Key Companies and Innovations in Denmark
- Coherent Corp. showcased next-generation optical solutions at ECOC 2025 in Copenhagen, including 2D VCSEL arrays for short-reach AI/ML datacenter interconnects and 100G ZR dual-laser QSFP28 DCO modules for single-fiber operation, enabling scalable, low-latency, and energy-efficient optical links .
- SENKO Advanced Components has been active in co-packaged optics, integrating detachable fiber connectors and 36-channel optical PIC connectors into high-performance networking switches, supporting AI, data center, and telecom applications .
- Local Danish photonics companies include SiPhotonIC, specializing in silicon photonic integrated circuits (PICs) for classical and quantum applications, and PeakOptical A/S, which manufactures fiber-optical components, transceivers, and xWDM solutions compatible with leading SFP and co-packaged optics standards .
Applications and Market Trends
CPO and co-packaged SFP solutions are increasingly adopted in high-speed data centers, AI/ML interconnects, and telecom networks. The integration of photonic ICs with electronic ICs in optical engines reduces copper trace lengths, lowers power consumption, and improves signal integrity, making these solutions ideal for next-generation optical networking . Denmark's photonics ecosystem supports rapid prototyping, scalable manufacturing, and integration of silicon photonics and SFP modules, positioning it as a hub for innovative optical interconnect solutions .
Summary
Denmark's co-packaged photonics SFP landscape is supported by global leaders like Coherent and SENKO, alongside local silicon photonics innovators. These companies provide high-speed, energy-efficient optical modules, detachable fiber connectors, and integrated PIC solutions suitable for AI, data center, and telecom applications. The combination of CPO technology, SFP modules, and silicon photonics enables Denmark to play a significant role in the development and deployment of next-generation optical networks .
