Inverse Designed Grating Coupler With Low Loss and High Bandwidth on LNOI Platform
A grating coupler structure on a X-cut lithium niobate on insulator (LNOI) platform is designed and demonstrated. The utilized inverse design method is based on gradient-based adjoint optimization method, which is time saving and with more optimization degrees of freedom. For TE polarization, the hi...
