A fast optical propagation technique for modeling micro-optical systems

Abstract

As designers become more aggressive in introducing optical components to micro-systems, rigorous optical models are required for system-level simulation tools. Common optical modeling techniques and approximations are not valid for most optical micro-systems, and those techniques that provide accurate simulation are computationally slow. In this paper, we introduce an angular frequency optical propagation technique that greatly reduces computation time while achieving the accuracy of a full scalar formulation. We present simulations of a diffractive optical MEM Grating Light Valve to show the advantages of this optical propagation method and the integration of the technique into a system-level multi-domain CAD tool.

Modeling and propagation of near-field diffraction patterns: A more complete approach

“…Modeling beam propagation within complex systems on this scale presents new challenges. 12,13 The aim of this paper is to discuss various diffraction theory models, probe the regions of validity of each, and apply appropriate models to some specific examples. The discussion could be incorporated into an advanced under graduate or beginning graduate level course in optics.…”

Comparison of Coaxial Holographic Storage Arrangements from the M Number Consumption Point of View

“…In our model, outside the storage material, the beams are calculated via scalar Fourier optical equations from SLM to the Fourier plane, and than propagated via scalar propagation technique based on ''plane wave spectrum'' from the Fourier plane to the material's top surface. 16,17) Inside the storage material, the beams for hologram writing and reconstruction processes are calculated by a scalar and fast Fourier transform (FFT)-based BPM. [8][9][10][11][12][13][14][15] Table I shows the main important parameters of the calculations.…”
