Causal Physics-Informed Neural Networks Training System For Physical Simulation
A computer-based training system improves physics-informed neural networks (PINNs) training by weighted residual loss terms to account for physical causality. Problem: Conventional PINNs can struggle with dynamical systems that show multi-scale, chaotic, or turbulent behavior. Existing formulations may fail to respect the spatio-temporal causal structure...

Monolithic White and Multi-Color Lasers Tunable in Full Visible Spectrum
Semiconductor lasers able to emit over the full visible color spectrum have a wide range of practical applications such as solid-state lighting, full-color displays, visible color communications, and multi-color fluorescence sensing. To the human eye, light with a mixture of four monochromatic lasers is visually equivalent to a white illuminant. Current...
