TFLN Crossing-v0
Three-Direction TFLN MMI Crossing Implementation/Optimization
Implement and optimize symmetric and asymmetric thin-film lithium-niobate MMI crossings at 1550 nm. Three independent crystal-direction subruns measure worst-direction insertion loss and enforce crosstalk and field-decay gates.

J_baseline = 0.04 dB · reference implementation-jbaseline-2026-09-28-v4. S = 1 means baseline parity; native evaluator gates, not S alone, determine score eligibility.
Provisional paper-simulation reference: approximately 0.040 dB from Figure 4(c), not the paper's measured 0.070 dB or a rerun in this evaluator. The archived evaluator's paper-gap diagnostic still uses the measured reference; reporting S uses the simulated-paper estimate above.
The saved final J is bound to the trusted evaluator manifest and exact Drive archive; this single-task publication 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).

TFLN MMI crossings
The symmetric and asymmetric mask sets are separated for clarity. All 22 slab and rib polygons come from the final GDS used in the trusted evaluation; colors are illustrative, not simulated fields.
Evidence chain
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.
