Abstract

Recently, an optical fractional Fourier transform (FRT) has been expected to apply to optical information processing. The FRT was first introduced by Namias in order to solve the harmonic-oscillator physical problem in quantum mechanics in 1980^[1]. McBride and Kerr improved the Namias's definition in 1987^[2]. In 1993, Ozaktas and Mendlovic introduced the optical FRT as the self-modes of a quadratic graded-index medium^[3]. Moreover, Lohmann pointed out that the FRT can be defined by an idea of the rotation of the Wigner distribution function (WDF)^[4].

In the present study, we introduce the fractional cross-spectral density (CSD), i.e., an idea of the FRT to the partially coherent optics. As an example, we theoretically analyze the CSD of the fractional optical field on a quasi-monochromatic Gaussian Schell-model (GSM) source.
