中文摘要：
用于加快量子绝热“慢”过程的量子绝热捷径技术,已广泛应用于原子、分子和光物理.基于耦合波导的量子光学类比,利用量子绝热捷径技术设计光学波导的耦合系数与传播常数,实现快速的光波导分束器件.通过数值模拟,并与共振耦合和绝热耦合波导进行比较.结果表明,量子绝热捷径技术所设计的光学波导分束器具有长度短、输出稳定性高的优势.
英文摘要：
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.
