Optimization campaigns, precursors, and audits#
Everything associated with inverse-designed cavities is collected here, including paused and negative campaigns.
Complete parameter → geometry → simulation → optimization → field-analysis notebook.
One source-driven single-pole waveform objective from a neutral start, followed only by pole tracking and a replay-gated smooth-boundary handoff.
A neutral full-domain 8 um Fryett search using six-component fields across pulse-on and source-off time windows, followed by a fail-closed eigenfrequency-shifted Q/V stage.
A z dipole in an immutable 1 µm air hole, optimized from a neutral radial line with exact m=0 cylindrical symmetry, robust projection, literal fields, and automatic pole surveillance.
The complete qualified-success record: every optimization stage, parameters, starting and final masks, paired fields, pole history, Pareto alternatives, and the robust-projection failure that ended the campaign.
The final literal-mask dashboard retained as a compact view of the stopped 780.24 nm Ez campaign.
The 780.24 nm Ey/TE-like one-sided coupler, with literal mask, field, beta, LDOS, Q, pole, and directional-loss telemetry.
The replacement z-dipole campaign: unit-cell gap, thickness screen, tapered post edge, PML stability audit, and full 3D Ez fields.
The stopped shifted-LDOS run, with its literal geometry, history, fitted pole, and Ey field.
The 780.24 nm single-etch campaign, paused at its last accepted checkpoint.
The original hard-gap free-form cavity campaign and its field evidence.
The guided-coupling-first campaign used to seed later pole optimization.
Fail-closed geometry, spectrum, branching-ratio, and density checks.
The historical LDOS-first campaign and diagnosed gray-material stall.
The independent evidence required before Q and Purcell targets are claimed.
The preserved 7.5 um no-slot beta-first campaign, including its final geometry, fields, and pole telemetry.
The unloaded paper geometry and remote-atom LDOS baseline used before shape optimization.
The parameterization and fabrication model for the observed ((( ))) family.
Thickness, spacing, apodization, oxide embedding, LDOS, and pole comparisons.
The controlled test of additional Bragg fronts at fixed transverse domain size.
The final live checkpoint from 795 LDOS and 294 bounded-beta updates.
Frozen 53.13% two-guide beta result with geometry, fields, channels, spectrum, and history.
The rejected 665-update initialization study and the evidence motivating gradual spectral discovery.
The stopped 20-update seed audit that exposed excess coordinate-axis spectral power.
A large 150 nm SiN design with 40,000 Fourier coefficients, a hard 1 um atom hole, and live fields.
