Abstract

The theory of Fourier Optics uses scalar diffraction models which provide simple, computationally efficient, and reasonably accurate tools for designing, optimizing and interpreting the performance of a wide range of devices and observed optical phenomena. Conventional approaches assume the time-separability of the relevant wave phenomena interpreted in terms of partial differential equations. Since light propagates in a time-dependent manner, certain mathematical formalisms must be injected to assure the validity of these methods. Moreover, in the case of two-dimensional propagation, the actual accuracy of the model suffers on account of the inherent time-dependent and diffusive nature of planar wave propagation. To resolve these imprecisions, we propose a “Time-Aware” approach to Fourier Optics and scalar diffraction, which closely matches the predictions of Fourier Optics for slowly changing input signals but accounts for a time-based error in integrated photonic devices with high clock speed.
