These 2D designs with finite thickness in the third dimension are often referred to as 2.5D. Full 3D photonic architectures, with refractive-index variations along the three dimensions, hold the promise of higher integration density and novel, to the best of our knowledge, light control capabilities, but require advanced multi-layer stacking techniques with precise alignment and planarization. Nanoscale 3D printing techniques, such as multi-photon lithography, can address these challenges, and are gaining momentum thanks to their cost-effectiveness and rapid prototyping capabilities compared to silicon foundries. Despite this potential, the exploration of freeform polymer optics at the nanoscale remains limited due to challenges associated with low-index materials and a lack of design tools. Here, we address these limitations by applying a multi-layered inverse design approach for polymer-based integrated optics. We systematically compare 3D with 2.5D designs (all simulations are conducted in 3D), for the task of demultiplexing two wavelengths with spectral spacing from 100 nm to 20 nm. Our numerical results show that fully 3D polymer designs consistently outperform their 2.5D counterparts, achieving higher efficiencies at equal footprint.

Although some deep-learning approaches train on synthetically added white Gaussian noise, real underwater scenes almost never provide clean ground-truth images, so the final result critically depends on the initial detected intensities. To address this, we present an intensity-correction protocol: two independent measurements are averaged, their noise variance is estimated on-the-fly, and a diagonal Wiener filter is applied to correct the intensities.

Our recent work [Nat. Commun.16, 6453 (2025)10.1038/s41467-025-61884-x] demonstrates that under continuous-wave excitation and in the absence of pure dephasing, the single-time joint state of resonance fluorescence and the two-level system can be described by a pure entangled state. Here, we analyze the cross-correlation and auto-correlation properties of the quantum optical field generated by the interference of resonance fluorescence with laser light at the resonance excitation frequency. Simulation results indicate that by varying the intensity or phase of the interfering laser light, the higher-order coherence of the post-interference quantum optical field transitions from anti-bunching to super-bunching behavior, consistent with recent theoretical and experimental advances by mean-field engineering.
