One of the fundamental numerical methods in photonics is the Finite Difference Time Domain (FDTD) method. FDTD discretizes Maxwell's equations to approximate the electromagnetic field propagation, providing a versatile framework for modeling optical systems. This method has played an instrumental role in designing and optimizing numerous photonic devices, including waveguides, lasers, and photonic crystals.

The Finite Element Method (FEM) is another powerful numerical technique widely used in photonics research. Originally developed for structural analysis, the FEM has been adapted to simulate light propagation and interaction with complex optical structures. By subdividing the optical domain into elements, the FEM can accurately model light behavior, enabling the design of advanced optical fibers, photonic circuits, and optical sensors.
