Designing Fiber Couplers with Rsoft

This paper demonstrates how a complex grating coupler design can be efficiently designed and optimized with a 2D decomposition and then validated by 3D simulation using the RSoft photonic simulation tools. 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. OptSim models single-mode fiber-based systems at the signal propagation level. OptSim Circuit is a modeling tool for next-generation photonic integrated circuits that operate with. In the process of studying and analyzing the spectral characteristics, the phase matching curve, that is, the relationship curve between the resonance wavelength and the grating period, is an indispensable link.
