Other simulation parameters and boundary conditions can be manually or automatically set.īelow is a dynamic near field pattern for a silver binary grating at different incident angles.Īfter the simulation, a steady state near field can also be observed in the field detector.īased on the near field properties, the far field transform tool is provided within the OptiFDTD software. I am looking for optical-simulator to simulate Dispersion of light using prism/Diffraction grating material with different wavelength of light. The third step is to set the output field detector by which we can observe the near field pattern and perform the far-field analysis. The user can also select a transverse beam pattern that can be a waveguide modal field, Gaussian beam, plane wave or user defined wave with various polarization properties. After we finish the layout creation, the next step is to set the incident wave properties: A time domain incident wave can be either a CW wave or a laser pulse which covers a relatively broad band. OptiFDTD provides several shapes to fill in the grating elements. There are two ways to design the periodic structure with OptiFDTD : The PBG editor enables us to design an arbitrary periodic lattice in 1D, 2D or 3D and Visual Basic scripting which allows us to code the periodic relation and element shapes. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams traveling in different directions. Ability to explore various diffraction devices.Multiple grating layout parameters can be optimized using parameter sweep simulations.This will significantly reduce the product development cost Advanced modeling can guide us to achieve the design goal quickly and efficiently.Wave sources and mediums are provided for water, sound, and light so users can compare the behavior of different types of waves. Additional tool boxes allow the simulation input and output to be linked to other optical tools like Zemax or Code V This interactive simulation allows users to explore the properties of waves.This gives us an in-depth understanding of the light wave interaction inside the diffraction element The dynamic near field can be simulated and displayed throughout the simulation.Photonic Crystal or semiconductor pixels.Light diffraction in the periodic or non-periodic geometry.
