研究了具有沟道和脊形截面的纳米硅波导在光纤通信波长附近的色散特性,并系统地研究了它们与波导关键结构参数的关系。仿真结果表明,在脊形波导深度上引入一个额外的自由度,使得脊形波导在群速度色散(GVD)的设计上比沟道波导更具有灵活性。此外,我们还得到了在1550 nm处实现零GVD的波导的结构参数。
We investigate the dispersion properties of nanometer-scaled silicon waveguides with channel and rib cross section around the optical fiber communication wavelength and systematically study their relationship with the key structural parameters of the waveguide. The simulation results show that the introduction of an extra degree of freedom in the rib depth enables the rib waveguide more flexible in engineering the group velocity dispersion (GVD) compared with the channel waveguide. Besides, we get the structural parameters of the waveguides that can realize zero-GVD at 1550 nm.
