Time-multiplexed networks constitute a versatile platform to extract benefits from the optical coherence linked to their high flexibility and reconfigurability as well as excellent efficiency and stability. Such time-multiplexing schemes show great potentials for fundamental studies as well as applications in quantum technology. Examples include quantum-walk, boson sampling, generation of large-scale cluster states, measurement-based quantum computing, to name only a few. In this study, we exploit our well-established fiber optical-loop design for time-multiplexing to synthesize the modal structure of the photon wave-packets and to test the quantum-classical nature of the involved optical states. We utilize single- and multiphoton quantum interference in the time-multiplexed network to recover both the modal structure and the quantum-classical nature of pulsed light.
