Error Analysis of Photonics Device
July 2000 - In a paper to be presented at SPIE in San Diego, ORA's Keith Doyle and William M. Bell of Topsfield Engineering Services perform a multi-tool analysis of a photonics device called an optical circulator. The paper, "Thermo-elastic wavefront and polarization error analysis of a telecommunication optical circulator," is based on simulations performed in MSC's NASTRAN and in C&R's Thermal Desktop software, with optical analysis done in CODE V.
NASTRAN was used for thermal and thermo-elastic analysis, with results converted into Zernike polynomial .INT files for import to CODE V. CODE V was used for both transmission analysis (including stress birefringence .INT modeling, new in CODE V 8.50) and fiber coupling efficiency. CODE V's ability to import surface deformations and stress birefringence changes combined with its polarization modeling capabilities to allow very sophisticated analysis of the perturbed system. This is a good demonstration of ORA's engineering and software capabilities for telecommunication device design and analysis. This paper is part of the session "Current Developments in Optical Engineering IX."
