BOOK
Ever since Einstein's special relativity in 1905, the principle
of invariant light speed in vacuum has been attracting attention
from a wide range of disciplines. How to interpret the principle
of light speed? Is light referred to continuous light, or light
pulse with definite boundaries? Recent discovery of superluminal
medium triggered vigorous discussion within the Physics
community. Can communication via such "superluminal channel"
break the speed limit and thus violate causality principle? Or
will a single photon, which is not governed by classical laws of
Physics, tend to break the speed limit? To solve these problems
in this Brief we bring in optical precursor, the theoretical
works for which started as early as 1914. This is a typical
optical phenomenon combining wave propagation theory and
light-wave interaction. Both theory and experimental works are
covered in this Brief. The study of precursor verifies that the
effective information carried by light pulses can never exceed
the speed of light in vacuum- c. Further, through observation
from nonclassical single photon source, the precursor rules out
the probability of a single photon traveling with the speed
breaking the classical limit
