LightSIM is high quality educational software which covers broad range of topics such as modal analysis in step index and graded index optical fiber, Spot size and offset losses calculation using various methods, attenuation, dispersion measurement for various refractive index profiles, modal analysis in multilayer symmetric and asymmetric planar waveguides, design of directional coupler using planar waveguides, Fiber optic link design etc. It has been designed in such a way that user can actually play with various input parameters, which helps user to learn the subject from fundamental to the advance level. Documentation and help menu containing with the LightSIM improve knowledge of user with better understanding of technical terms related to the subject. Using LightSIM user can visualize various complex optical phenomena through graphs and animations.

LightSIM helps in better understanding of following concepts

  •   How an optical fiber works and what are the important parameters of a fiber?
  •   What is fiber mode, how it looks?
  •   How to find out total number of modes by seeing the graphs and how to control number ofmodes in an optical fiber to make it single mode fiber?
  •   What is dispersion, how it behaves and how it affects fiber performance?
  •   What is attenuation, different types of attenuation and how it limits fiber performance?
  •   How to design a graded index (GI) fiber, what are the important parameters of a GI fiber,Modes in a GI fiber?
  •   Dispersion measurement in GI fiber, W-type fiber and dual core fiber.
  •   Symmetric and asymmetric TE/TM modes of a planar waveguide
  •   How to control number of modes by optimizing various input parameters in a planarwaveguide?
