- <p><span>In-plane video recording of the fabrication of a four-layer woodpile structure by simultaneous dual-plane two-photon polymerization (2PP). The video shows the polymerization process as seen from above the focal plane, where 29 write spots distributed across two distinct planes (separated by 1.8 µm) simultaneously produce polymerized lines during continuous scanning. The spot arrays are arranged along opposite diagonals: 15 spots in the first plane and 14 interleaved spots in the second plane, each generating parallel lines with a 3 µm spacing. The multi-spot pattern is produced by a single static diffractive optical element (DOE) combining two independently computed phase masks with a Fresnel phase term for focal-plane separation. Fabrication was performed at a scan speed of 5 mm/s with a laser output power of 300 mW (515 nm, 1 MHz). This video accompanies the paper "Simultaneous Dual-Plane Multi-Write-Spot Two-Photon Polymerization Using a Single Diffractive Optical Element" presented at SPIE Photonics Europe 2026.</span></p>
