We cite various examples of normal mode splitting and avoided crossing in quantum optical and plasmonic systems. We show how this generic phenomenon can
be exploited to generate fast and slow light. We cover some of the very recent experiments. The last part of the lecture focuses on the Belinfante's transverse spin,
which is attracting a lot of attention in past couple of years. We demonstrate how the transverse spin can be further enhanced by means of coherent perfect absorption.
