Bacteriorhodopsin (bR) is a photosensitive protein that shows remarkable anisotro This photoinduced anisotropy enables one to record the polarization hologram.We proposed a new photonic switching device with erasable focusing lens, Zone Plate, using bR.The arrangement employed to obtain the Zone Plate is Mach-Zehnder interferometer using 515 nm line of Ar-ion laser. In one of the write beams, a spherical lens is inserted. At the exit of the interferometer and at a determined distance, the bR film is placed on which the circular Zone Plate is recorded by means of the coherent superposition of thr plane and spherical wavefronts. Probe beams that have different wavelength travel with one of the write beams and irradiates the Zone Plate, which forms images of light source points respectively.Using above Zone Plate, we demonstrated the wavelength demultiplexer and optical switching where information is carrued by orthogonal polarization states.

细菌视紫红质（bR）是一种光敏蛋白质，具有显著的各向异性，这种光致各向异性使人们能够记录偏振全息图，我们提出了一种利用bR制作的带可擦除聚焦透镜的新型光子开关器件--波带片，波带片的制作采用马赫-曾德尔干涉仪，波长为515 nm。在一个写入光束中，插入球面透镜。在干涉仪的出口处和一定的距离处，放置bR膜，在其上通过三个平面波前和球面波前的相干叠加来记录圆形波带片。不同波长的探测光随其中一束写入光入射到波带片上，波带片分别形成光源点的像，利用波带片实现了波长分波器和光开关，其中信息由正交偏振态传输。
