We present an optical quantum random number generator based on vacuum fluctuation measurements that uses multi-mode coherent states generated by electro-optical phase modulation of intense carrier. In this approach the weak state (or a state) interferes with carrier, which acts as local oscillator, each side mode independently. The proposed setup can effectively compensate for deviations between two arms balanced detector controlling index modulator. perform proof-of-principle experiment and demonstrate generation possibility real-time randomness extraction at rate 400 Mbit/s.
