英文摘要： As a kind of quantum coherent devices, all-optical quantum device produced by the nonlinear interaction of atoms and light in light- matter coupled system, can be used to control the coherent transmission of the photons in the constrained system and photonic network, not only has the traditional optics feature such as optical isolator, light mirror, etc., but also exhibit the physical characteristics like diode, transistor, and other electronic component. The biggest difference with traditional devices is that all-optical devices can be easily coupled to the quantum information processing systems, to achieve all-optical manipulation of quantum states, which promote the development of quantum information technology to the practical direction of integration and networking. On th basis of our experimental research about atomic coherence and four wave mixing effects ,this project is mainly researching the all-optical devices and their characteristics based on atomic gas, and the primarily method is through optical refractive index modulation induced by atomic coherence in the cesium atomic system coupled by the bicromatic fields. Our research contents are as follows:1) In the EIT medium, the experimental research of optical device effects such as optical diode, optical transistor and mirror, and so on; 2), The exper
