Efficiency Enhanced Grating Coupler for Perfectly Vertical Fiber-to-Chip Coupling

In this work, a bidirectional grating coupler for perfectly vertical coupling is proposed. The coupling efficiency is enhanced using a silicon nitride (Si(3)N(4)) layer above a uniform grating. In the presence of Si(3)N(4) layer, the back-reflected optical power into the fiber is diminished and coup...
