摘要
We propose an efficient and low-power second harmonic generation(SHG)process in a silicon-compatible hybrid plasmonic microring resonator.By making the microring resonator doubly resonant at the fundamental wavelength of 3.1μm and second harmonic wavelength of 1.55μm,the SHG efficiency is enhanced by almost two orders of magnitude when compared to the previous result induced in a straight plasmonic waveguide.A SHG efficiency of 13.71%is predicted for a low pump power of 20 mW in a ring with radius of 2.325μm.This device provides a potential route for realizing efficient frequency conversion between mid-infrared and near-infrared wavebands on a chip.
