Enschede, 16 March 2026. Aluvia Photonics has demonstrated negligible polarization dependent gain (<0.5 dB) in their advanced PIC‑EDWA platform.

Polarization‑dependent gain (PDG) is a critical performance metric in optical communications. Even small gain differences between polarization states can degrade signal quality, limit transmission reach, and increase DSP complexity in high‑capacity, high‑data‑rate coherent links. This challenge is especially acute in hyperscale AI datacenter interconnects, where performance margins are narrow and power budgets are tightly constrained. Achieving low‑PDG amplification is therefore essential to maintain signal stability and maximize overall system throughput.

Combined with its demonstrated high gain (30 dB of internal net gain) and low noise figure (4.5 dB), this new result marks a major breakthrough for Aluvia’s PIC‑EDWA technology in integrated optical amplification. It enables robust performance in polarization‑multiplexed coherent systems and opens the door to scalable, low‑power, high‑capacity optical architectures required for next‑generation AI and cloud networking.

“Low‑PDG performance has long been a challenge in integrated amplifiers,” said Ward Hendriks, CTO of Aluvia Photonics. “By achieving less than 0.5 dB PDG while maintaining high gain and low noise, we are eliminating a key barrier to fully integrated optical systems capable of meeting tomorrow’s data‑scaling demands.”

Aluvia Photonics will showcase its PIC‑EDWA technology at the Optical Fiber Communication Conference (OFC) in Los Angeles (US), where visitors can see the PIC-EDWA technology, meet the team, and learn how PIC‑EDWA can unlock new levels of efficiency and scalability for AI networks and next‑generation datacenter interconnects.
