Elementary functions: propagation of partially coherent light.
The theory of propagation of partially coherent light is well known, but performing numerical calculations still presents a difficulty because of the dimensionality of the problem. We propose using a recently introduced method based on the use of elementary functions [Wald et al. Proc. SPIE6040, 59621G (2005)] to reduce the integrals to two dimensions. We formalize the method, describe its inhe...
متن کاملTailored Anderson localization with partially coherent light
Anderson localization and partially coherent light are at first sight unrelated, if one thinks in terms of interference. However, Anderson localization can be observed with non-coherent light, since a partially coherent beam can be viewed as a superposition of randomly phased components, which localize independently in a disordered media [1]. This gives rise to the question of how much transver...
متن کاملCoupled simulation of chemical lasers based on intracavity partially coherent light model and 3D CFD model.
Coupled simulation based on intracavity partially coherent light model and 3D CFD model is firstly achieved in this paper. The dynamic equation of partially coherent intracavity field is derived based on partially coherent light theory. A numerical scheme for the coupled simulation as well as a method for computing the intracavity partially coherent field is given. The presented model explains ...
متن کاملOptimal 3D phase-shifting masks in partially coherent illumination.
Gradient-based phase-shifting mask (PSM) optimization methods have emerged as an important tool in computational lithography to solve for the inverse lithography problem under the thin-mask assumption, where the mask is considered a thin two-dimensional object. As the critical dimension printed on the wafer shrinks into the subwavelength regime, thick-mask effects become prevalent and thus thes...
متن کاملSpatial correlation vortices in partially coherent light: theory
Coherent optical beams may contain optical vortices that are characterized by a dark core and a well-defined azimuthally harmonic phase.1,2 In contrast, different points in a spatially incoherent beam are uncorrelated, and the phase structure of an optical vortex is ill defined. In the transitional regime of partially coherent light, one should take the statistical properties of light into acco...
