Toward Topology-Optimized Foundry PDKs: A Seeded Design Framework for Multimode Interferometers
Jacob M. Hiesener, Archana Kaushalram, Joshua J. Wong +2
We present an end-to-end design methodology for multimode interferometer (MMI)-based photonic devices that combines parameter optimization (PO) on analytical models with seeded top…
Unifying and accelerating level-set and density-based topology optimization by subpixel-smoothed projection
Alec M. Hammond, Ardavan Oskooi, Ian M. Hammond +3
We introduce a new "subpixel-smoothed projection" (SSP) formulation for differentiable binarization in topology optimization (TopOpt) as a drop-in replacement for previous projecti…
Seeded Topology Optimization for Commercial Foundry Integrated Photonics
Jacob M. Hiesener, C. Alex Kaylor, Joshua J. Wong +2
We present a seeded topology optimization methodology for integrated photonic devices fabricated on foundry platforms that yields improved performance compared to traditional topol…
Integrated Photonic Topology Optimization with Nonvertical Sidewall Profiles: Applications in Lithium Niobate and Silicon
Michael J. Probst, Jacob M. Hiesener, Archana Kaushalram +1
We enable density-based topology optimization (TO) to design integrated photonic devices featuring nonvertical sidewall profiles. Specifically, we demonstrate TO for fabrication pr…
