Interface with Ray Tracing Tools
Tool Used: BeamPROP, CODE V
Typically a lens system may be simulated efficiently using raytracing techniques, but these become inaccurate when the geometry size scale is on the order of the wavelength of interest. In that case, more rigorous techniques such as the Beam Propagation Method or Finite-Difference Time-Domain are required. Hybrid simulation using multiple techniques can be achieved via the passing of field data between simulators, as shown here in this simple lens to fiber coupling example where the lens is analyzed via ray-tracing (RTA) and the fiber via beam propagation, BeamPROP BPM.
RSoft tools contain an interface to convert the output from industry-standard raytracing packages such as CODE V and Zemax.
As an example, the amplitude and phase information constructed from the output rays of a ball lens rendered in CODE V are shown here.
These proprietary formats are converted by the RSoft Raytracing Interface to input files that are ready to be used in RSoft Simulation tools. Furthermore, output from RSoft simulations can be converted to formats understandable by CODE V and Zemax.
