The Detector Amplified the Signal, Not the Noise
A proposed intracavity quadrature cycle increased gravitational-wave response without accumulating parametric gain.
Summary
A proposed intracavity quadrature cycle increased gravitational-wave response without accumulating parametric gain.
The design alternates amplification and deamplification over two round trips in a detuned recycling cavity. Modeling a current detector with a near-future upgrade showed broader quantum-noise-limited sensitivity into the kilohertz band; it remains a proposal, not an installed upgrade.
Why it matters
A proposed intracavity quadrature cycle increased gravitational-wave response without accumulating parametric gain.
Limits and context
- Modeling a current detector with a near-future upgrade showed broader quantum-noise-limited sensitivity into the kilohertz band; it remains a proposal, not an installed upgrade.
