Home / Fdtd Case Study Polarization Splitter
In this session, we will demonstrate the capabilities of Optiwave's finite-difference time-domain (FDTD) tool by walking through the setup, execution, and analysis of a polarization beam splitter model sourced from literature. When the TM0 mode is launched at the input end, it is efficiently converted into the TE1 mode at the tapper and then coupled to the TE0. This is to certify that the thesis titled Design of Polarization Splitter and Rotator, submitted by Sireesha Nambigari R, to the Indian Institute of Technology, Madras, for the award of the degree of B. Tech (Dual Degree), is a bona fide record of the research work done by her under my.
