Abstract

Abstract

Research on the optical coherence manipulation has made significant progress, but the modulation rate of conventional tailoring technology is too low, which has become a key factor hindering its transition from laboratory to practical application. Here, we utilize lithium niobate films (LNF) modulator to achieve high-speed optical coherence manipulation based on its high-speed electro-optical modulation capability. Our experimental modulation rate reaches 350 kHz, which is about 20 times higher than the fastest modulation rate reported so far. This design strategy provides a simple rule for high-speed optical coherence manipulation based on electro-optical modulation, paving the way for further practical applications of optical coherence manipulation technology.
