Dual Dynamic
Gain Equalizer

Silicon Oxynitride (SiON) reconfigurable filter for EDFA gain flattening

PhotonPath’s Dual Dynamic Gain Equalizer (DDGE) is a compact, low-loss integrated photonic device device for optical gain flattening in amplified networks.

Built on PhotonPath’s proprietary low-loss SiON platform, the module integrates fully reconfigurable filters, that dynamically adapt to guarantee spectral flatness and high optical performance.

DDGE extends usable bandwidth enabling a single amplifier to replace three or four amplifier nodes while reducing noise, complexity, cost and power consumption.

USE CASES

Applications & Network Impact

Dynamic Gain Equalizers play a critical role in enabling efficient, reliable, and scalable operation in next-generation optical networks.

In systems with multiple amplifiers, effective management of gain tilt and gain ripple is essential to preserve signal quality across all wavelength channels. By providing real-time gain control, DGE supports flexible network configurations, and reduce reliance on complex signal processing.

Performance

Tilt Profiles

The DGE can operate as a dynamic compensator of linear tilts of ± 10 dB. Channel tilt in optical communication systems could be induced by diverse effects such as ISRS (Inter-channel Stimulated Raman Scattering) and wavelength-dependent fiber gain/loss.

Evaluated Flatness

Defined as the difference between the target profile and the DGE implemented spectral response.
