The proposed project aims to investigate a novel grating coupler structure for efficient polarization andwavelength independent fiber-to-waveguide coupling. Grating couplers are widely used as input/output portsthat provide the optical interfaces between optical fibers and the photonics circuit. The commercialfiber-to-planar waveguide grating couplers are both polarization and wavelength dependent. The proposedresearch project first involves extensive numerical design of a grating coupler that potentially offers both thepolarization and wavelength independence features. Dr. Winnie Ye's research group will team up with thetechnical group of Optiwave, who will provide technical support for their specialized three-dimensionalOptiFDTD and OptiSpice software for the simulation needs. Rigorous simulations of the device design will becarried out to obtain the most optimal design parameters and device performance, followed by design masklayout creation. The research team plans to fabricate the prototype device in the near future to facilitate thevalidation of the accuracy and effectiveness of the Optiwave Photonic Software. If successful, this joint projectwill provide a versatile grating coupler for general use in silicon photonic circuits.

本计画旨在研究一种新颖的光栅耦合器结构，以实现与波长及偏振无关的光纤-波导耦合。光栅耦合器被广泛用作输入/输出端口，提供光纤和光子电路之间的光学接口。商用的光纤-平面波导光栅耦合器既依赖于偏振又依赖于波长。提出的研究项目首先涉及广泛的数字设计的光栅耦合器，可能提供偏振和波长独立的功能。温妮博士的研究小组将与Optiwave的技术小组合作，他们将为专门的三维OptiFDTD和OptiSpice软件提供技术支持，以满足模拟需求。将对器件设计进行严格的模拟，以获得最佳的设计参数和器件性能，然后创建设计掩模布局。研究团队计划在不久的将来制造原型设备，以便于验证Optiwave光子软件的准确性和有效性。如果成功的话，这个联合项目将为硅光子电路提供一个通用的光栅耦合器。
