| Abstract: | Shortcuts to adiabaticity have been proposed to accelerate “slow” adiabatic processes with the applications in atom, molecular and optical physics. Based on the quantum optical analogy of coupled waveguide, the coupling coefficient and propagating constant are designed by using shortcuts to adiabaticity, to realize optical beam splitters in short length. Compared with resonant and adiabatic couplers by numerical simulation, the designed waveguide is demonstrated its advantages on shorter length and high stability. |
