Using Phase Screens to Synthesize Electromagnetic Gaussian-Schell Model Sources With Desired Amplitude, Coherence, and Polarization

Abstract

An electromagnetic Gaussian-Schell model (EGSM) source is built with desired coherence, amplitude, and polarization using correlated phase screens based on research conducted in Refs. [2,9]. A new method of amplitude control is presented and tested using spatial light modulators (SLM). A brief review of theory and concepts is discussed followed by methods of how to build an EGSM source, correlated phase screens, and control amplitude using SLM gratings. The experimental set-up is presented which builds EGSM sources that demonstrate desired amplitude, coherence, and polarization. Correlation, degree of polarization, and Stokes parameters S0 and S1 are examined and compared to theoretical predictions to validate experimental results. The results are summarized and future work is discussed including methods of calculating and measuring Stokes S2 and S3.
