  bibo_abstract:
  - Light-emitting diodes (LEDs) are becoming increasingly important across various
    sectors of the lighting industry and are being used more frequently. In the field
    of symbolic projection, research is increasingly focusing on implementing light
    modulation using energy-efficient, incoherent LEDs rather than lasers. Since light
    modulation in micro- and nano-optics is typically achieved through phase modulation,
    Finite-Difference Time-Domain (FDTD) simulations are employed for analysis. The
    objective of this article is to investigate different approaches for approximating
    incoherent monochromatic light sources within FDTD simulations. To this end, two
    approaches based on dipole sources are considered, as well as a method involving
    plane waves with modulated wavefronts based on Cosine–Fourier functions and a
    method based on the superposition of Gaussian beams. These methods are evaluated
    in terms of their accuracy using a two-dimensional double-slit configuration and
    are compared against a fully incoherent analytical reference.@eng
