Complex wavefront engineering via decoupled space-time modulation

Anna Wirth-Singh, Arka Majumdar, Johannes E. Fr\"och, Virat Tara

A metasurface doublet integrated with a photonic integrated circuit optical phased array decouples electrical modulation from the optical plane, enabling independent 2D control and a threefold reduction in effective pixel pitch for solid-

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

By integrating a metasurface doublet with a PIC-based OPA, we achieve independent 2D electrical control over each phase-element while simultaneously realizing a three-fold reduction in effective pixel pitch.

C2weakest assumption

The metasurface doublet successfully decouples the electrical and optical planes without introducing unacceptable losses, phase errors, or crosstalk that would prevent the claimed independent control and pixel-pitch reduction.

C3one line summary

A metasurface-PIC hybrid decouples electrical control from optical output to achieve high-speed, high-resolution 2D wavefront engineering in solid-state SLMs.
