Abstract
Conventional optical imaging is limited by diffraction, preventing discrimination of closely spaced incoherent sources. Inspired by quantum parameter estimation, this thesis explores spatial-mode demultiplexing (SPADE) as a method to overcome this limit by projecting light onto an orthonormal mode basis. In this work, we design and experimentally validate a practical implementation of spatial-mode demultiplexing via Multi-Plane Light Conversion (MPLC).
