| Abstract: | 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. |
