摘要: Abstract Metal-confined III–V circular nanoresonator coupled to a waveguide-connected silicon is proposed for realizing guided emission. The mode characteristics are investigated by the three-dimensional (3D) finite-difference-time-domain (FDTD) method. output performance can be greatly improved through optimizing parameters of and underlying nanoresonators. For 750-nm-radius hybrid covered SiO2 Ag layers, an extraction efficiency 26% Q factor 680 obtained as radius 75 nm larger than nanoresonator.
