Time-domain beam propagation method and its application to photonic crystal circuits
抄録
A time-domain beam propagation method (BPM) based on the finite-element scheme is described for the analysis of reflections of both transverse electric and transverse magnetic polariaed pulses in wavegniding structures containing arbitrarily shaped discontinuities. In order to avoid nonphysical reflections from the computational window edges, the perfectly matched layer boundarv condition is introduced. The mesent algorithm usine the Pade approximation is, to our knowle-dge, the Krst time-domain beam propagation method which can treat wide-band optical pulses. After validating this method for an optical grating with modulated refrative indexes, various photonic crystal circuit components are simulated.
