K2 Photonics · K2-1000
A gigahertz dual-comb system without the locking stack
A shared-cavity architecture generates both combs in a single resonator. Because the two combs share the cavity, their intensity, timing and phase noise are highly correlated — which removes the need for high-speed locking electronics and optical amplification that conventional dual-comb setups depend on.
What the shared cavity buys you
- Passive mutual coherence: no active locking loop to tune, drift or lose.
- Highly correlated intensity, timing and phase noise between the two combs.
- No optical amplification stage, so fewer components between the laser and the experiment.
- Optical delay is swept without any mechanical stage, so extended delays are scanned fast.
- Solid-state design with ultra-low relative intensity noise for sensitive measurement at high frequencies.
