摘　　要：将发光器件和硅光电负阻器件面对面地封装在一起 ,其间实现电隔离 ,构成一种新型光耦合器。由于光电负阻器件具有双稳和自锁特性 ,这种非线性光耦合器具有响应保持功能。文章以PDUBAT为例从实验方面证实了响应保持功能的存在 。A new type of photo isolator has been developed by packing light emitting devices with silicon photo negative resistance devices face to face to realize electrical isolation. With the bistability and self locking of the silicon photo negative resistance devices, these non linear photoisolators exhibit response maintaining function for the input signal. The demonstration of response maintaining function on PDUBAT is made experimentally and the realization of response maintaining function on PLBT is proposed
