Applications of Beam Propagation and Finite Difference Time Domain Techniques in Photonics Simulations


The bidirectional beam propagation method extends the beam propagation method (BPM) to simulate general reflective photonic devices, retaining the efficiency of BPM. Its primary applications include laser-facet, anti-reflection/high-reflection coatings, gratings, etc. I will talk a bit more of its application to VCSEL designs. In photonic device computations where BPM solutions are not adequate, Finite-Difference Time-Domain (FDTD) is usually the method of choice. Despite its accuracy and flexibility, FDTD is very time consuming. The recently proposed ADI-FDTD technique is one effort to increase the efficiency of FDTD. Based on it, my current work is to further improve it to gain more substantial speed-up. The demonstration is being done on photonic crystals.
