The POLYNICES paper “InP/Si3N4 Hybrid Integrated Lasers for RF Local Oscillator Signal Generation in Satellite Payloads” is now available online.
This research introduces a compact, tunable multi-laser module that generates multiple radiofrequency (RF) signals for satellite communications. By integrating five hybrid lasers on a single chip and using micro-ring resonators for precise wavelength control, we achieved simultaneous RF signal generation in the Ka- and V-bands—both crucial for high-speed satellite links. The device offers a wide tuning range, ultra-stable signals with narrow linewidths, and scalability to produce up to 10 RF signals at once. This breakthrough provides a compact, efficient solution for next-generation high-throughput satellite systems.
