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…

Inverse-Designed Tapers for Compact Conversion Between Single-Mode and Wide Waveguides
Michael J. Probst, Arjun Khurana, Archana Kaushalram +1
Waveguide tapers are critical components for leveraging the benefits of both single-mode and wide waveguides. Adiabatic tapers are typically hundreds of microns in length, dramatic…
