"thin-film lithium niobate breaks speed limit for visible modulators... control individual photons encoded with quantum information... Mach-Zehnder interferometer modulators with push-pull configuration... <1 V modulators. larger shifts further slow modulator’s drive pulse color of light... sensing, AR/VR, data communications and quantum internet... improve electro-optic bandwidth to 100 GHz... reduce optical loss... route individual photons to many solid-state quantum memories and convert light wavelength"
