Compact, Broadband, and Wide-Angle Optical Coupling for Silicon Waveguide
A novel grating coupling scheme with simultaneously broadband and wide-angle efficiency for unidirectionally coupling freely propagating light into a silicon waveguide is proposed and theoretically investigated. The coupling structure is composed of two cascaded subgratings with proper spectral and...
