We present an ultra-compact metal reflector based grating coupler for coupling light between optical fiber and nano photonic waveguides. The coupler is designed and simulated based on Finite Difference Time Domain (FDTD) method. The lateral dimension of the grating waveguide has been tapered down from 10 μm to 400 nm within 8 μm length to(More)
