Photonic chip synthesizes flexible millimeter-wave signals
—
What the study found The study found that a silicon photonic chip paired with a reconfigurable optical frequency comb can synthesize millimeter-wave signals. The system supports on-chip filtering and modulation and can produce single-frequency, multi-frequency, and vector signals for arbitrary IQ signal construction. Why the authors say this matters The authors say photonics-assisted millimeter-wave and…
