Optus has been develop with the objective of rapid and flexible design and simulation of electromagnetic, photonic and optical structures, and for it to be easy to use by both students and professionals alike. The interface contains all the necessary inputs and controls at the ready, all being clear in their purpose and easy to access. Features of Optus include:
-
Employs an optimized and stabilized rigorous coupled wave algorithm (RCWA) that provides detailed information on the optical properties of the structure (e.g., reflection, transmission, diffraction, scattering, field configurations, integration with far-field analysis tools, and assessment of cross-polarization effects and other complex optical behavior)
-
Use of the Ray parallel processing Python package to vastly increase the speed of calculations
-
The use of Plotly graphics to create informative and visually appealing graphics and field animations
-
A materials catalog that provides immediate access to important optical constants (i.e., n and k as a function of frequency) for a wide range of commonly used materials.​
-
The ability to export data as a .json file to allow for post-processing with a variety of other computational tools (e.g., Matlab, Zemax)
Complex shapes can be created by combining many child shapes and using Boolean operations.
Choose one of the 5 Bravais lattices for two dimensionally periodic structures
Wavelength scans are quick and easy to set up, allowing for immediate calculation of reflection, transmission, diffraction efficiencies, and absorption.
