Compact double-part grating coupler for higher-order mode coupling
We propose and demonstrate a compact and efficient grating coupler for first-order mode fiber-to-chip coupling. The coupler is configured by a double-part grating structure combined with a curved Y-junction by means of mode diversity. Compared with a traditional grating coupler, the designed structu...
