Encode in geometry
In the proposed architecture, input data selects a controlled spiral-pitch state. The current prototype uses controlled vortex-element rotation to generate distinguishable experimental states used to investigate this architecture.
Experimental proof
Measured on the bench, not presented as a theoretical claim.
The prototype uses a laser, spatial filtering, a Michelson interferometer, a vortex lens and camera-based spatial detection.
Prototype demonstration: controlled optical states produced distinct interference signatures that were successfully classified at the receiver.
STATIC CLASSIFICATION
98.9%
89/90 frames correctly classified using four regions of interest (leave-one-out nearest-centroid).
SEQUENCE DECODING
93.3%
28/30 symbols correctly decoded in the held-out ±60° sequence (180 frames, six per symbol).
ROBUSTNESS CHECK
27 / 27
Correct classifications after mount rotation, part of the robustness diagnostic chain.
Experimental results shown above are measured laboratory results from the current prototype and do not represent a commercial transmission-rate claim.
Repeated measurements
Distinct states across repeated measurements
Representative experimental detector frames across five measurement configurations. The interference signatures remain distinguishable across repeated trials.
