Generation of stochastic electromagnetic beams with complete controllable coherence

Abstract: We generate a stochastic electromagnetic beam (SEB) with complete controllable coherence, that is, the coherence degree can be controlled independently along two mutually perpendicular directions. We control the coherence of the SEB by adjusting the phase modulation magnitude applied onto two crossed phase only spatial light modulators. We measure the beam's coherence properties using Young's interference experiment, as well as the beam propagation factor. It is shown that the experimental results are consiste… Show more

“…Several optical elements, including rotating ground glass (RGG), dielectric elastomeric actuator, and spatial light modulator (SLM), are adapted to impose the random phase. [14][15][16][17] The disadvantage of an RGG is that the random phase is difficult to be quantitatively controlled. Although using an SLM can quantitatively control the coherence of the light, the coherence of the light remains invariant in most of the studies.…”

“…The degree of polarization represents the relevance of two rectangular components of the electric field at one single point [18][19][20]. In 2003, a unified theory of coherence and polarization was proposed [21], and this is highly advantageous for in-depth study of the spectrum, coherence and polarization of the beam [22][23][24]. The electromagnetic Gaussian Schell-model (EGSM) beam is a classical partially coherent vector beam and any point in this field has the same polarization [25][26][27][28][29][30].…”

“…The spatial light modulator (SLM) is a common instrument for beam manipulation in the experiment. It is widely used in the field of modern optics, such as designing light sources with specific phase and amplitude distribution, generating partially coherent beams [11,12] and simulating turbulence media [13][14][15]. Hence, considering using SLM to generate rotatable beams could easily come to mind.…”
