How to Count Modes and Deduce Limits in Optics

This invited talk at Metamaterials 2021 discusses how we can use the new kind of “modes”, formally given by the singular value decomposition (SVD) of the coupling operator, to describe optical communications and linear optical devices efficiently and precisely. This approach uniquely gives all the orthogonal channels between input and output spaces. It leads to… Read more How to Count Modes and Deduce Limits in Optics
