摘要

We present a theoretical analysis of light pulse delay in resonant photonic bandgap structures made from Bragg-spaced semiconductor quantum wells. Quantum well Bragg structures offer the possibility for parametric manipulation of the polariton band structure. This, in turn, may be used for stopping, storing, and releasing of light pulses. Based on a theoretical model utilizing a time-dependent transfer matrix approach to the solution of Maxwell's equations, we study light pulse propagation, light pulse trapping and releasing, and light pulse deformation in these structures. We discuss the photonic band structure concepts relevant to our light delay scheme and present numerical simulation results of pulse delay through presently existing quantum well Bragg structures.
