Observation of Anticorrelation with Classical Light in a Linear Optical System
Two-photon anticorrelation is observed when laser and pseudothermal light
beams are incident to the two input ports of a Hong-Ou-Mandel interferometer,
respectively. The spatial second-order interference pattern of laser and
pseudothermal light beams is reported. Temporal Hong-Ou-Mandel dip is also
observed when these two detectors are at the symmetrical positions. These
results are helpful to understand the physics behind the second-order
interference of light.Comment: 5 pages, 4 figures. Comments are welcom
Smoothness of multivariate refinable functions with infinitely supported masks
AbstractIn this paper, we investigate the smoothness of multivariate refinable functions with infinitely supported masks and an isotropic dilation matrix. Using some methods as in [R.Q. Jia, Characterization of smoothness of multivariate refinable functions in Sobolev spaces, Trans. Amer. Math. Soc. 351 (1999) 4089–4112], we characterize the optimal smoothness of multivariate refinable functions with polynomially decaying masks and an isotropic dilation matrix. Our characterizations extend some of the main results of the above mentioned paper with finitely supported masks to the case in which masks are infinitely supported
