腔模红移对非线性微腔双稳态阈值的影响

影响非线性微腔双稳态阈值的因素很多,例如电介质折射率、周期数、缺陷层厚度、谱线宽度等。但是腔模红移起到了十分重要的作用。从理论上分析了红移对双稳态阈值的影响,并作了数值模拟。红移是研究双稳态阈值首先要考虑的问题。

Ultra-Low Threshold Optical Bistability and Multi-Stability in Dielecrtric Slab Doped with Semiconductor Quantum Well

A scheme for switching of the optical bistability(OB) and multi-stability(OM) in a dielectric slab doped with a three-level ladder-configuration n-doped semiconductor quantum well is simulated. It is shown that the bistable behavior of the system in dielectric slab can be controlled via amplitude or relative phase of applied fields. This optical system may provide some new possibilities for test the switching process.
