Pulse-Generation Maps in External-Cavity Semiconductor Lasers with Short-Delay Optical Feedback

We investigate pulse generation in external-cavity semiconductor lasers subject to short-delay optical self-feedback using a deterministic quadrature-based delay-differential model. High-resolution pulse-generation maps are constructed in the (lg(C),ϕf) parameter space, where lg(...

Spatially validated physics-guided residual learning for indoor path loss prediction

Accurate indoor path loss prediction requires models that remain physically interpretable while capturing the structured variability introduced by walls, clutter, and non-line-of-sight propagation. This paper presents a physics-guided residual-learning framework for indoor path l...
