Specular and antispecular light beams

Abstract: We consider a class of spatially partially coherent light beams, which are generated by passing a Gaussian Schell-model beam though a wavefront-folding interferometer. In certain cases these beams are shape-invariant on propagation and can exhibit sharp internal structure with a central peak (specular beam) or a central dip (antispecular beam) whose dimensions depend on the spatial coherence area. Such beams are demonstrated experimentally and their cross-like distributions of the complex degree of spatial coh… Show more

“…In order to synthesize asymmetric Schell-model source in equation ( 4), the phase correlation function of the SLM should take forms of equation ( 15) in [19]. Furthermore, specular and anti-specular optical fields generated in a WFI have been demonstrated experimentally [26], hence the transformation of asymmetric Schell-model incident fields with a WIF can be realized in laboratory according to the methods described in [26]. The results obtained in this work are of particular importance in which fields where nontrivial intensity patterns are required, such as periodic trapping of micro-particles and free-space communications.…”

“…Figure 1 exhibits the device of a WFI, which is mainly used for spatial coherence measurements of partially coherent light fields [26]. The key elements of this Michelson-type interferometer are the two crossed oriented right-angle prisms P1 and P2 in the arms, which retroreflect the incident beam in x direction and y direction, respectively.…”

“…Since that time, scalar DAD partially coherent sources (PCSs) have been experimentally realized using the source's coherent-mode representation [3,4] and by passing a J 0 -Bessel correlated PCS [5][6][7] through a wavefront-folding interferometer [8,9]. In another recent paper, the authors showed that DAD beams could be realized from stochastic optical fields that are the weighted sums of randomly tilted plane waves [10].…”
