摘　　要：Parity-Time(PT)symmetry is an emerging concept in quantum mechanics where non-Hermitian Hamiltonians can exhibit real eigenvalues.Now,PT symmetric optical microresonators have been demonstrated to break the bandwidth-efficiency limit for nonlinear optical signal processing.

关 键 词：SYMMETRY LIMIT BREAKING
