To overcome the current lack of large-size single crystal cBN difficulties caused by the investigator

CBN linear electro-optic effect and ultraviolet effects research process and findings. First, two aspects of the theory are described, followed by combining the characteristics of the material itself gives a detailed experimental program, and the experimental  Diamond blade  the main narrative, and finally combined with theoretical analysis of the experimental results. In this thesis, to overcome the current lack of large-size single crystal cBN  synthetic diamond  caused by the investigator, according to the tiny size of the actual shape of cBN crystal devised a cBN crystal tiny considering the size and shape of the octahedral sheet electrode device, in the classic transverse electro-optical modulator based on the structure of the modulator made ​​some adjustments.
