rf-acoustic-multimode-optical-operator — operator-supplied RF/acoustic optical operator proposal
Minimal decisive protocol
RF/acoustic operator matrix test
Drive a multimode optical medium with independently logged RF and acoustic controls, reconstruct the complex mode-to-mode operator, and compare it with a field-off and single-control model.
- Calibrate RF phase, acoustic delay, and modal readout.
- Run randomized control waveforms and basis-mode inputs.
- Acquire complex output modes and synchronized drive logs.
- Compare full, RF-only, acoustic-only, and field-off operators.
Decision rule: The joint operator claim survives only if full-control outputs require the joint drive model beyond each ablation.
Controls
- ablated: RF drive only. (acoustic drive; Joint operator contribution should be absent.)
- ablated: Acoustic drive only. (RF drive; Joint operator contribution should be absent.)
Observables and units
Observables| Observable | Units | Measurement | Uncertainty reporting |
|---|
| complex mode operator | dimensionless | basis-resolved complex transfer matrix | report phase, delay, and detector covariance |
|---|
| control-to-output latency | ns | cross-correlation of logged drive and output | timestamp and sampling uncertainty |
|---|
Calibration and repetitions
- RF/acoustic relative delay: common trigger and reference pickup — delay residual below phase-equivalent tolerance (ns)
Replicate unit: independent control waveform; minimum 30, independent 6.
Randomization: waveform, basis mode, and control order randomized
Stopping rule: complete balanced control blocks
Uncertainty: drive phase noise, acoustic delay, modal cross-talk, medium drift; complex transfer covariance with synchronized nuisance traces; publish all control waveforms and raw outputs
Success and falsifiers
Success
- The jointly driven operator is not explained by the RF-only, acoustic-only, or field-off controls. (held-out model residual < predeclared margin normalized residual)
Falsifiers
- An ablated or linear model predicts the joint output within the same tolerance. (residual improvement <= predeclared threshold fraction)
Required capability groups
- control · required, any-one, quantity 1: independently phase-logged RF and acoustic controller (system) — synchronized drive logs and safety interlocks
- independent-pickups · optional, at-least-n, quantity 2: independent RF phase pickup (channel) — independent source and pickup trace
- independent-pickups · optional, at-least-n, quantity 2: independent acoustic delay pickup (channel) — independent transducer pickup and timestamp
Related capability types: Independent RF/acoustic multimode controller
Confounds and raw artifacts
- a shared electrical driver creates an unlogged joint channel: independent pickups and timing audit; mitigation: separate source and shield paths
- synchronized-drive-and-mode-trace · binary acquisition plus JSON · retain raw timestamps and waveform hashes
Nonclaims
- A measured operator is not evidence of a new physical law.
- No optical processor performance or deployment is claimed.
Provenance boundary
The citation supplies acousto-optic context only; it does not support a joint RF/acoustic operator claim.
