摘要

弯曲波导耦合器的轴线会导致耦合波导之间的相位失配。利用弯曲波导耦合器，实现了相位失配符号翻转的波导间绝热光传递的捷径。紧凑型耦合器对参数变化具有较强的鲁棒性。

Compact and Robust Bent Axis Waveguide Coupler with a Sign Flip of the Phase Mismatch

Bending the axis of a waveguide coupler results in phase mismatch between the coupled waveguides. Using a bent waveguide coupler, we realize shortcut to adiabatic light transfer between waveguides with a sign flip of the phase mismatch. The compact coupler is robust against parameter variations.
