光栅耦合器作为光纤和纳米绝缘体上硅(SOI)波导之间的接口,在耦合效率和对准公差方面表现出了良好的性能。在本文中,我们回顾了我们以前的工作,其中实现的光纤芯片光栅耦合器的微米脊SOI波导中的第一次,显示测量的耦合效率为-2.2dB的横向电(TE)偏振。我们还提出了一种新的光栅设计,实现了计算的耦合效率为-2dB的横向磁(TM)光。
Grating couplers have shown promising performance in terms of coupling efficiency and alignment tolerances as an interface between optical fibers and nanometric silicon-on-insulator (SOI) waveguides. In this paper we review our previous work, where the implementation of a fiber to chip grating coupler in micrometric rib SOI waveguide was demonstrated for the first time, showing measured coupling efficiency of -2.2dB for transverse-electric (TE) polarization. We also propose a new grating design that achieves a calculated coupling efficiency of -2dB for transverse-magnetic (TM) light.
