摘要
A method was demonstrated for slowing light signals in electro-optical periodically poled lithium niobate. A forbidden band gap can be formed when the transverse electric field exceeds zero. The group velocity of a light near the band gap can be delayed via changes in electric field strength or wavelength, with a maximum delay of 20 ns in the experiment, which is attractive for electro-optical signal processing and all-optical signal processing.
