In the last fiscal year we demonstrated successfully that the output from photorefractive four wave mixing (FWM) could be switched by externally applied electric field. The switching speed was much faster than usual photorefractive four wave mixing switch in which index grating is rewritten at every switching occasion, but the speed could not be measured because of slow response of our photo detector.In this fiscal year we tried to measure the speed and found that the response time was shorter than that of our pulse generator whose response time was of the order of 10μs. Then, we analyzed switching operation of output from self pumped phase conjugate mirror (SPPCM) by externally applied electric field and successfully demonstrated it.Also, we theoretically analyzed wavelength selection and pixel selection of photorefractive output by externally applied electric field. The results were promising for wavelength selection and for pixel selection.

在上一财年，我们成功证明了光折变四波混频（FWM）的输出可以通过外部施加的电场进行切换，其切换速度比每次切换时都会重写索引光栅的普通光折变四波混频开关快得多。偶尔，但由于我们的光电探测器响应速度慢，无法测量速度。在本财年，我们尝试测量速度，发现响应时间比我们的脉冲发生器的响应时间短，脉冲发生器的响应时间约为10μs。然后，我们分析了外加电场对自泵浦相位共轭镜（SPPCM）输出的切换操作，并成功进行了演示。此外，我们还从理论上分析了外加电场对光折变输出的波长选择和像素选择，结果令人鼓舞。用于波长选择和像素选择。
