在双Lamder模型中实现可调控光子带隙
Tunable photonic bandgap in double Lamder configuration
摘要
Abstract
We investigate a four level double lamder system with spontaneously generated coherence ( SGC) for achieving photonic band gaps ( PBG) by a standing-wave field. When the coupling field is far away from reso-nance or resonant, we can obtain one-phonon bandgap or two-phonon bandgap due to spontaneous emission coherent from two decay pathways. When the SGC is absent, the probe field is absorbed by the medium, so the PBG cannot be generated. The numerical calculations show that the induced PBG result from the Kerr nonlinear modulation between the probe and coupling field, and by controlling the detunings of coupling field, one PBG can be dynamically tuned into two PBGs in this system.关键词
