- Paper accepted! 🥳 "Explaining and exploiting the radial memory effect in multimode optical fibres" (A slightly older version is on ArXiv: arxiv.org/abs/2508.11389 ) 1/3 💡 ⚛️ 🧪 #OpticalFibers
- When (coherent) light propagates in a multimode fibre, each mode accumulates a slightly different phase, so the output looks like a random speckle patter. But it is NOT random! This non-randomness has a number of consequences. 2/3
- We show that a focused input will always result in a ring of excess intensity at the same radius of the input, we give a simple but rigorous explanation of why this happens, and suggest how this might be useful in practice. 3/3Jan 9, 2026 11:40
