Right Device, Right Place: Variation-Aware Placement and Design Optimization for Robust Photonic Lattice-Filter Demultiplexers
arXiv:2607.14526
summary
The paper introduces a Bayesian co‑optimization framework that jointly optimizes device placement and design parameters for integrated photonic lattice‑filter demultiplexers, enhancing robustness to fabrication and thermal variations and achieving improved spectral matching with lower calibration power.
Abstract
We propose a Bayesian co-optimization framework for robust integrated photonic lattice-filter demultiplexers, jointly optimizing device placement and design parameters under fabrication and thermal variations. Results show 75% better spectral matching and 45% lower calibration power.
