Abstract

With means of parametric space, obtained from Parity-time (PT) symmetric transfer matrix, Lorentz reciprocity theorem, and non-imaginary of Bloch phase, we discuss the conditions of wave propagation, coherent perfect absorption-lasing (CPAL), and bidirectional transparency occurred at finite periodic PT-symmetric waveguide networks.
