Exciting progress on the ALLEGRO project! The first run of our IQ modulators is currently undergoing testing, and we anticipate meeting our predicted KPI targets.

Despite some unexpected fabrication challenges causing minor delays, the completion of this stage ensures no major impact on the second run.

πŸ’‘ Key Highlights from Internal Runs:
βœ… 3-dB Bandwidth: Over 100 GHz
βœ… Data Transmission: 774 Gb/s 64-QAM over 100 km fibre
βœ… 16-QAM Symbol Rates: 192 GBd (SD-FEC) | 140 GBd (HD-FEC)
βœ… Projected Performance: Beyond 1 Tb/s per lane with dual-pol IQ

With a fibre-to-fibre insertion loss of 17.8 dB and VΟ€ of 4V, further design optimizations confirm that the ALLEGRO KPI targets are within reach! πŸ“ˆ

As we move forward, improvements in fibre-to-chip coupling efficiency will further enhance performance. Stay tuned for more updates as we continue pushing the boundaries of high-speed optical communication!
