In our latest development, the ALLEGRO project continues to push the limits of high-speed photodetection. Previous results from RP1 demonstrated a flat electro-optical response up to 100 GHz and consistent responsivity in the C-band.
π‘ Key Highlights from This Run:
β
Targeting 500 mA/W responsivity
β
Achieved 70 mA/W, a 25Γ improvement over [Koe23]
β
PDs tested with 4-PAM modulation at 96 GBd
β
Next step: 125 GBd 16-QAM single-lane demonstration
While improvements in responsivity have been significant, further design and fabrication optimizations are underway to meet ALLEGROβs ambitious KPIs while maintaining optimal voltage levels.
Stay tuned as we drive innovation in high-speed optical communication! π‘π‘
