Tasks
Explore functional-requirement design problems and reference-grounded implementation challenges. Published entries open the complete run evidence; empty entries establish the released catalog without inventing results.
Anisotropic SWG-v0
Anisotropic SWG 2 x 2 Beamsplitter Implementation/Optimization
Implement and optimize an anisotropic subwavelength-grating 2 × 2 MMI beamsplitter over 1250–1750 nm. One input is simulated; strict y-mirror symmetry establishes the second input response.
α-Si/Si₃N₄ Grating-v0
α-Si/Si3N4 SWG Grating Coupler Implementation/Optimization
Implement and optimize the apodized α-Si/Si₃N₄ SWG grating at 1310 nm. Trusted FDTD measures coupling loss and both bandwidths against the paper-derived reference envelope.
Dual-Trident SWG-v0
Dual-Trident SWG Edge Coupler Implementation/Optimization
Implement and optimize a silicon dual-trident subwavelength-grating edge coupler over 1536–1628 nm. The trusted evaluator measures Gaussian-beam coupling into the output waveguide's fundamental TE mode.
HMDM polarization splitter–rotator
HMDM Polarization Splitter–Rotator Implementation/Optimization
Optimize the paper-derived polarization splitter–rotator's independently selectable nanohole sites. The trusted evaluator measures desired-mode transmission for TE₀ and TM₀ inputs across 1500–1600 nm.
HMDM six-channel WDM
HMDM Six-Channel WDM Binary Optimization
Optimize a six-channel WDM nanohole mask with independently selectable sites across the paper-derived design region. The trusted evaluator measures worst-channel insertion loss and crosstalk against the paper envelope.
Sb₂Se₃/Si Rotator-v0
Sb2Se3/Si Reconfigurable Polarization Rotator Implementation/Optimization
Implement and optimize a reconfigurable Sb₂Se₃/Si polarization rotator. The trusted evaluator scores worst-case polarization-conversion loss over both material states and 1290–1330 nm.
SRSN Grating-v0
SRSN Grating Coupler Implementation/Optimization
Implement and optimize a silicon-rich silicon nitride grating above a thin SiN waveguide for vertical fiber-to-chip coupling at 1550 nm. Compare evaluator-owned coupling loss with the paper’s 3D-FDTD baseline.
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.
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.
Trapezoidal SWG-v0
Trapezoidal SWG 2 x 2 3-dB Coupler Implementation/Optimization
Implement and optimize a trapezoidal subwavelength-grating 2 × 2 coupler. Compare both physical input responses over 1400–1700 nm against the paper’s splitting and excess-loss envelope.
