This paper reviews a number of optical gyroscope architectures utilizing either slow or fast light that have been recently
proposed in the literature to enhance rotation sensitivity, with a view to separate the schemes that offer a genuine
enhancement from the ones that do not. The overall conclusion is that although slow-light coupled-resonator systems
have interesting applications in other fields, for example for filtering or switching, none of the schemes proposed to date
enable any enhancement in rotation sensitivity. Simple guidelines are outlined in an attempt to help clear misconceptions
and hopefully reduce the number of erroneous publications on this subject in the future. On the other hand, fast light in a
ring laser gyro can potentially enhance rotation sensitivity by up to six orders of magnitude. Future research directions
likely to be fruitful are also outlined.read more
