• Reliability-Aware Bayesian Optimization of 1310 nm PCSELs with FDTD Verification

  Jinglin Yu, Feiyang Wu, Longying Wen, Chongxian Yuan, Renjie Li, Zhaoyu Zhang · 27. Juli 2026

  Near 1310 nm photonic-crystal surface-emitting lasers (PCSELs) are attractive narrow-beam sources for optical communication and sensing, but their final design refinement is costly. Small geometry changes simultaneously shift the band-edge resonance, cavity leakage, far-field divergence, and the num…

• Self-attention-based non-linear basis transformations for compact latent space modelling of dynamic optical fibre transmission matrices

  Yijie Zheng, Robert J. Kilpatrick, David B. Phillips, George S. D. Gordon · 18. Juni 2026

  Multimode optical fibres are hair-thin strands of glass that efficiently transport light. They promise next-generation medical endoscopes that provide unprecedented sub-cellular image resolution deep inside the body. However, confining light to such fibres means that images are inherently scrambled …

• Mirror Bridges Between Probability Measures

  Leticia Mattos Da Silva, Silvia Sell\'an, Francisco Vargas, Justin Solomon · 24. Februar 2026

  Resampling from a target measure whose density is unknown is a fundamental problem in mathematical statistics and machine learning. A setting that dominates the machine learning literature consists of learning a map from an easy-to-sample prior, such as the Gaussian distribution, to a target measure…

• LayerSync: Self-aligning Intermediate Layers

  Yasaman Haghighi, Bastien van Delft, Mariam Hassan, Alexandre Alahi · 20. Februar 2026

  We propose LayerSync, a domain-agnostic approach for improving the generation quality and the training efficiency of diffusion models. Prior studies have highlighted the connection between the quality of generation and the representations learned by diffusion models, showing that external guidance o…
