Summary: 
This letter describes a highly sensitive broadband electric field sensor that uses a LiNbO3 optical modulator. A broad-band, low driving-power optical modulator and high-power optical source are used to achieve high sensitivity. The minimum detection level of 1 mV/m and band-width of 1GHz are obtained.
