Here we experimentally demonstrate the dynamics of Bloch-Zener oscillations (BZOs) in a synthetic temporal lattice formed by optical pulses coupled fiber loops. By periodically modulating phases imposed to linear driven lattices, two-band Floquet system with tunable bandgaps is realized, and related BZOs that occurred this are displayed.
