Optical Waveguide Design with OnScale Cloud Engineering Simulation
In this webinar, we discuss how to simulate optical waveguide devices and postprocess results in OnScale, the cloud engineering simulation platform.
Waveguide devices can serve various functions, such as transporting signals, splitting, mixing, multiplexing and filtering. As the performance of such devices is frequency-dependent, we will carry out parametric sweeps in the software to choose an optimum geometry for signal propagation at the 1310 and 1550 nm optical wavelengths, both for straight and curved waveguides. We will also investigate the study of an evanescent waveguide coupler for filtering applications and explore its stability against manufacturing variations via a Monte-Carlo simulation.
Traditionally analytical or reduced-order models have been the only practical means to design optical waveguide devices due to the complexity and computational size of full 3D simulations. However, full time-domain simulations (supported by OnScale) are desired for complete characterization of such devices, including spurious modes and dispersion or resolution of fine and unique geometrical structures. OnScale offers an electromagnetics solver that has been specifically developed to face these challenges and solve system-level wave propagation problems in the time-domain, providing a full suite of wideband spectral results.
