Abstract:
In the current review, the implications of experiments, on superluminal and subluminal light propagation, in various types of artificially prepared optical media, have been analyzed and discussed in detail. In addition, the theoretical interpretations of the reported experimental results, which are being put forward within the framework of several physical theories, in this field, have been thoroughly examined. Subsequently, it has been concluded that, even though the two leading interpretations, on the basis of the hypothesis of quantum tunneling and the Sommerfeld-Brillouin-Stenner hypothesis, might facilitate the integration of the above experimental results, into the prevailing physical paradigms, neither hypothesis could possibly encourage further inquiries into the far-reaching implications of those experiments, or assist in finding the actual physical mechanisms behind them.
