本文首次提出一种由相干度非线性调制得到的新型光学双稳态——空间双稳态及其作用无耦合和有交叉耦合情况下,经γ/υ和υ/ν变换反馈可得到多种形式的双稳态,且给出了几种情况下的稳态特性方程、参数选择区域以及翻转条件等.

Optical coherence bistability (transverse optical bistability) arised from the nonlinear modulation of coherence and its experiment arrangement is first reported in this paper. Calculation and theoretic analysis show that many kind of optical bistability can be obtained in different conditions such as γ/ν or ν/v feedback, with orosscoupling between two dimension coherence signal or without coupling. The stable stable state equations, appropriate parameter range and switch conditions in several situation are given. This kind of optioal bistability may be used in picture enco:iingy optioal oalonlation. and quan bfioation of degree of spatial coherence.
