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