Durable and programmable ultrafast nanophotonic matrix of spectral pixels.

ABSTRACT: Locally addressable nanophotonic devices are essential for modern applications such as light detection, optical imaging, beam steering and displays. Despite recent advances, a versatile solution with a high-speed tuning rate, long-life durability and programmability across multiple pixels remains elusive. Here we introduce a programmable nanophotonic matrix consisting of vanadium dioxide (VO₂) cavities on pixelated microheaters that meets all these requirements. The indirect Joule heating of these VO₂ cavities can result in pronounced spectral modulation with colour changes and ensures exceptional endurance even after a million switching cycles. Precise control over the thermal dissipation power through a SiO₂ layer of an optimized thickness on Si facilitat
