摘要
采用电磁诱导透明技术可以实现慢光速,其对应正常色散(dn/dω>0或dng/dω>0),而采用电磁诱导吸收技术可以实现超光速甚至负群速,其对应反常色散(dn/dω<0或dng/dω<0).目前慢光速和超光速的研究已成为相对论、量子力学、电子学和信息论等交叉学科的研究热点.
Electromagnetically induced transparency (EIT) technology can be used to achieve slow speed of light corresponding to normal dispersion (d n/d ω〉0 or d ng/d ω〉0),and electromagnetically induced absorption (EIA) can be used to achieve ultrafast light or even negative group velocity of light corresponding to anomalous dispersion (d n/d ω〈0 or d ng/d ω〈0. The study of ultraslow light and ultra:fast light is of interest in the research of the theory of relativity, quantum mechanics, electronics and the theory of information.
