contents Based on the quantum mechanical "Shortcut-to-Adiabatic passage" (STAP), a novel design for the efficient and robust multiple beam splitter is presented in this paper. This multiple beam splitter consists of one input and $N$ output waveguide channels, which are connected via a mediator waveguide (WG). To implement "STAP" but without additional couplings, this $(N+2)$-WG system is first reduced to a controllable $3$-WGs counterpart by "Morris-Shore" (MS) transformation. Consequently, the reduced system can be directly compatible with all possible "STAP" methods. The results show that this novel design can achieve arbitrary ratio of multiple beam splitting and can significantly shorten the length of the device, which expands the application of "STAP" in classical system and provides a direct visualization in space of typical ultra-fast phenomena in time. More uniquely, this new design exhibits a one-way energy transport behavior. These may have profound impacts on exploring quantum technologies for promoting advanced optical devices.
