Flexible Control of Temporal Reflection and Refraction via Joint Parameter Modulation
Achieving the flexible control of wave propagation is a central goal in the design of optical devices. In this work, our analytical results and numerical simulations show that in both the two-legged model and SSH model, joint modulation of coupling strengths and phases enables independent control of the probability partition and the propagation opening angles in the space-time map. We hope these results could provide a theoretical foundation for the design of programmable time-modulated optical devices.
