Title: Spatial Mode Sorting And Its Applications In Super Resolution Imaging
Abstract:
When talking about imaging, a known limit is the Rayleigh resolution limit [1]. This limit means
that at the sub-Rayleigh regime (≈ λ/D ) the intensity profile of any object looks like an airy disk
magnitude squared. Therefore, direct imaging cannot resolve sub-Rayleigh object features.
In recent years, spatial mode demultiplexing (SPADE) has been identified as a promising tool
to enhance the quantitative performance of super-resolution (or sub-Rayleigh) imaging. SPADE is
a pre-detection process that separates different spatial modes of a light beam into individual output
channels. This process allows us to take out the component of the field in the image plane that lives
inside the airy disk and lets us detect them as light in higher-order modes.
During my Ph.D. I have worked to realize the super-resolution advantages that spatial mode sort-
ing offers experimentally. In this proposal, I will lay down the basic theory behind my experimental
work, discuss the experiments and results that have already been achieved, and present the proposed
framework for the remains of my Ph.D.
