Abstract :
Based on the typical microcavity quantum property and integration of the planar microtoroid with ultra-high Q value(about 108), this paper theoretically proposes the design of the micro-optical voltage sensor. The voltage sensor belongs to the field of MOEMS, the entire device is composed of one microtoroid (diameter from 60 mum to 120 mum) with the ohmic contact in the middle and a fiber taper waveguide. Through contact dot the outside detected voltage is connected with the ohmic contact, as a result of the ohmic contact heat effect, the external voltage signal through the device transforms into a strong frequency shift which is coupled out through the fiber taper waveguide. After that it will be showed on the photoelectric detector and then the voltage value under test could be calculated.
