Once a humble insulator, silicon nitride (Si₃N₄) now powers the future of photonics and quantum tech. With ultra-low optical loss, wide transparency, and CMOS compatibility, it enables on-chip frequency combs, quantum light sources, and scalable 3D circuits. From handheld spectrometers to quantum interconnects, Si₃N₄ is the backbone of next-gen optical systems—blurring lines between classical and quantum photonics.
