TFLN PI-MMI-v0
Polarization-Insensitive TFLN 1x2 MMI Implementation/Optimization
Implement and optimize a polarization-insensitive TFLN 1 × 2 MMI. The trusted evaluator measures worst-output excess loss for TE and TM across 1520–1580 nm.

J_baseline = 0.2497000433601877 dB · reference implementation-jbaseline-2026-09-04-v3. S = 1 means baseline parity; native evaluator gates, not S alone, determine score eligibility.
The eligible final J is bound to the trusted evaluator manifest and exact Drive archive. This single-task result does not grant task-release or official campaign authority.

The final submission cleared every trusted gate and was scored.
Individually approved single-task run, not an official campaign result or task-release certification. The final score and intermediate probes come from the retained trusted evaluator evidence. Download the verified run archive (HDF5 intentionally excluded).

Polarization-insensitive TFLN 1 × 2 MMI
Top-view polygon reproduces the final scored GDS mask. The same geometry was evaluated in separate TE and TM coupons; the x-cut TFLN stack is an evaluator-defined schematic, not a simulated field.

Why this result is reported this way
Native evaluator geometry validation; this is not a foundry DRC or LVS sign-off.
The exact final submission cleared the trusted gate sequence.
Official J is authoritative; baseline-normalized S is shown only after score eligibility.
How to interpret this result
A valid outcome means the submitted artifact cleared the evaluator gates recorded for this archived run. It does not imply that every possible physical specification, fabrication condition, or later task revision has been independently re-tested.

Reporting score S vs. time
S is derived from each eligible raw J at its observed elapsed time. Hollow baseline markers are unscored attempts, not S = 0.
