Parity-time symmetry in wavelength space within a single spatial resonator

Most conventional PT-symmetric systems contain two physically separated modes. Here the authors proposed a PT-symmetric microwave optoelectronic oscillator, where the gain and loss modes are confined in a single spatial resonator, resulting in an increased structural simplicity, and long-term stabil...
