摘要

我们报道了一种2x2 3db绝热耦合器，耦合器间隙为400 nm，锥长为90 μm。设计的弧形锥度使耦合器的长度比传统的直线锥度短8倍。该器件在1580 ~ 1620 nm波长范围内具有50±2%的功率分裂比。

2x2 Silicon Photonic 3-dB Adiabatic Coupler with Optimized Taper Curvature

We report a 2x2 3-dB adiabatic coupler with the coupler gap of 400 nm and the taper length of 90 μm. The designed curved taper enables 8-times shorter coupler length than a conventional line ar taper. The fabricated device exhibits 50 ± 2% power splitting ratio over the wavelength range from 1580 nm to 1620 nm.
