To embed thermal reconfigurability directly into an inverse-design optimization framework to produce compact, multifunctional silicon photonic devices within a single footprint.
Coupled adjoint-based topology optimization with the intrinsic thermo-optic response of silicon to co-optimize multifunctional optical geometries.
Designed, fabricated, and experimentally tested a compact optical switch and a reconfigurable TE0–TE2 spatial mode converter.
Achieved low optical insertion loss of less than 2 dB across both representative devices.
Demonstrated robust, thermally programmable multi-functionality with high agreement between numerical simulations and experimental measurements.
