The discussion centers on the origin of the group delay equation in the context of Linearly Chirped Fiber Bragg Gratings (LCFBG). The participant references a specific document, identified as reference 21, which provides limited information. For a comprehensive understanding of group delay in LCFBG, the participant suggests consulting the paper available at http://arxiv.org/pdf/physics/0604091.pdf. This source is crucial for grasping the underlying principles and mathematical formulations related to group delay.
