Chirality sensing employing parity-time-symmetric and other resonant gain-loss optical systems
Chirality sensing employing parity-time-symmetric and other resonant gain-loss optical systems
Molecular chirality detection and enantiomer discrimination are very important issues for many areas of science and technology, prompting intensive investigations via optical methods. However, these methods are hindered by the intrinsically weak nature of chiro-optical signals. Here, we investigate and demonstrate the potential of gain materials and of combined gain-loss …
