We propose a novel sensivity enhancement technique for electro-optic (EO) sensor. In convetional EO sensing systems, balanced detection is used to enhance their sensitivity. The proposed technique realized sensitivity
enhancement with constant received light intensity by reducing the carrier component and increasing the modulation depth of received light. Thus, saturation of photodiodes and shot noise limit in balanced detection are avoided. We successfully achieved sensitivity of 0.23 mV/Hz$^{1/2}$ by an EO sensor based on the technique. |
