本文讨论一种有发展前景的光敏生物材料－细菌视紫红质(菌紫质)，采用化学增强法制备菌紫质膜，利用Z扫描技术测量了菌紫质膜的非线性光学参数，结果表明菌紫质具有大的非线性光学系数，在光信息处理领域有十分广泛的应用．
We present a unique biological material that exhibits interesting photochromic characteristics and important optoelectric properties. This distinctive material is related to the visual pigment rhodopsin and is called bacteriorhodopsin (bR). In this paper the films of the chemically enhanced bacteriorhodopsin are prepared and the effective nonlinearity n2 of the film is measured with the Z-scan Technology. Anomalous absorption at three wavelengths is observed. Large optical nonlinearities of bR should be useful for both information storage and compulation.
