GDS is intuitively easy to use with just two separate Graphical User Interface (GUI) windows and a limited amount of required settings. The aim of GDS is not only to simulate Fiber Bragg Gratings, but also to provide the end-user the parameters to continue fabricating the. Optiwave software can be used in different industries and applications, including Fiber Optic Communication, Sensing, Pharma/Bio, Military & Satcom, Test & Measurement, Fundamental Research, Solar Panels, Components / Devices, etc. OptiSystem is a comprehensive software design suite that enables. Optimize the performance of your photonic applications with RSoft GratingMOD CMT, a general design tool that rapidly simulates complicated grating profiles in optical fibers and integrated waveguide circuits. GratingMOD efficiently powers CMT or coupled mode theory analysis. We used the FDM Fibre Solver to calculate the modes for the cylindrically symmetric designs A and B and the FDM Solver for the non-cylindrically symmetric design C. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. Sol Photonics has bundled years of experience of Fiber Grating design and manufacturing into an easy to use software package which we named GDS (short for Grating Design Software).
