Abstract: | Second harmonic generation is a nonlinear optical process that is an important bridge in the conversion between infrared and visible light. A ring resonator with a top layer of aluminum nitride, a material with high second order susceptibility, can achieve an efficient coupling between 780 nm visible light and 1550 nm infrared light. A tapered region is also integrated to improve the light transmission between an optical fiber and an on-chip waveguide. We demonstrate the high value of nonlinear coupling interaction strength, the phase matching of the mode extraction from the waveguide to the ring resonator, and the fabrication of tapered optical fiber and tapered aluminum nitride waveguide. |
