Observation of parity-time symmetry in time-division multiplexing pulsed optoelectronic oscillators within a single resonator
文献摘要：
In recent years,parity-time(PT)symmetry in optoelectronic systems has been widely studied,due to its potential applications in lasers,sensors,topological networks,and other fields.In this paper,a time-division multiplexed pulsed optoelectronic oscillator(OEO)is proposed to study the dynamics of a PT symmetry system.Two micro-wave pulses are used to realize the PT symmetry in a single spatial resonator based on the temporal degrees of freedom.The gain and loss of the microwave pulses and the coupling coefficient between them can then be con-trolled.We first demonstrate the phase diagram from PT broken to PT symmetry in the OEO system.We theo-retically prove that the perturbation of a coupling-induced phase shift larger than(2π)×10-2 causes the disappearance of the PT symmetry.In this experiment,the perturbation is less than(2π)×0.5×10-2;thus,the phase transition of PT symmetry is observed.In addition,multipairs of PT-symmetry pulses indicate that pulsed OEO could be used to implement complex non-Hermitian Hamilton systems.Therefore,it is confirmed that pulsed OEO is an excellent platform to explore the dynamics of PT symmetry and other non-Hermitian Hamiltonian systems.
