| Abstract: | A precise optical power measurement method is introduced in this paper to detect the optical path loss. In this study, a mathematical model is catered to analyze optical power and current characteristics (P-I) of the PIN electrooptic cells. Accordingly, it is observed that a quite high measurement precision can be obtained within a range from -60 dB to 0 dB (attenuation value relatively of optical power). |
