This dissertation addresses one of the tools used for measuring the properties of light in optical devices. This instrument can locally probe the light to assess its phase and amplitude at precise locations, providing critical information. The primary focus of this work is to enhance the height feedback for the probe's positioning, develop a procedure for the simultaneous measurement of orthogonal polarizations in free-space beams, and formulate an algorithm for the polarization-resolved assessment of guided modes in a bus waveguide-ring resonator system.
