Abstract

摘要 利用染料分子带模型,探讨了染料环形腔系统的光学双稳特性,得到光学双稳可在一个比较大的频率范围内实现;其双稳区域是染料分子带结构参数(带宽及偶极分布的Lorentzian宽度等)的函数. Abstract The optical bistability in a dye ring cavity has been investigated. It is shown that the bistability can be realized in a much wider frequency range, and that the bistable regions are functions of the band structures (the bandwidth and the distri-bution of dipole moments). 作者及机构信息 龚尚庆1, 徐至展1, 潘少华2, 杨国桢2 (1)中国科学院上海光学精密机械研究所; (2)中国科学院物理研究所 Authors and contacts GONG SHANG-QING1, XU ZHI-ZHAN1, PAN SHAO-HUA2, YANG GUO-ZHEN2 (1)中国科学院上海光学精密机械研究所; (2)中国科学院物理研究所 参考文献 施引文献

Stability analysis for an optical bistable dye system

Shangqing Gong, Shao-hua Pan, Guo-Zhen Yang

A different set of the Maxwell-Bloch equations describing optical bistability in a dye ring cavity has been derived. A complete linear stability analysis including propagation effects is given. The corresponding numerical simulations show that the bistable regions are functions of both the frequency detuning and the band-structure parameters such as the bandwidth and the distribution of the dipole moments.

Optical bistability in a dye-ring cavity

Shangqing Gong, Shao-hua Pan, Guo-Zhen Yang

The optical bistability in a dye-ring cavity has been investigated by using the derived Maxwell-Bloch equations based on the band model. It is shown that the bistable conditions and behavior are closely related to the band structure of the dye molecules.

摘要 本文运用Kroning-Penney 模型新形式, 研究超晶格子带间光吸收的三阶非线性效应, 发现不论量子阱参数(如阱宽、垒宽和垒高等)如何改变, 光吸收饱和强度与隧穿谱宽之间存在着一种较普遍的关系, 并阐明了这种依从关系的物理机制. Abstract By means of a new formalism of the Kronig-Ponney model developed recently, the third order nonlinear optical effect of intersubband transition In superlattices is studied. It is shown that there is a general relation between optical saturation intensity and tunnel bandwidth. The physical mechanism of this relation is analyzed. 作者及机构信息 潘少华;冯思民;崔大复;杨国祯 1. 中国科学院物理研究所, Authors and contacts Pan Shao-hua Feng Si-min Cui Da-fu Yan Guo-zhen 参考文献 施引文献

Optical bistability: towards all-optical devices

Eusebio Bernabéu, Pedro Martín Mejías, R Martínez-Herrer

The phenomenon of optical bistability is the object of increasing interest owing to its possibilities for important device applications. The object of this short review is to give a description of this current field either from its conceptual theoretical basis or from its applications on optical circuitry and computing. Contents include three sections devoted to optical instabilities, bistable materials and international programs on this topic.
