Nano-resonator integrated with two-dimensional materials (e.g. transition\nmetal dichalcogenides) have recently emerged as a promising nano-optoelectronic\nplatform. Here we demonstrate resonatorenhanced second-harmonic generation\n(SHG) in tungsten diselenide using a silicon photonic crystal cavity. By\npumping the device with the ultrafast laser pulses near the cavity mode at the\ntelecommunication wavelength, we observe a near visible SHG with a narrow\nlinewidth and near unity linear polarization, originated from the coupling of\nthe pump photon to the cavity mode. The observed SHG is enhanced by factor of\n~200 compared to a bare monolayer on silicon. Our results imply the efficacy of\ncavity integrated monolayer materials for nonlinear optics and the potential of\nbuilding a silicon-compatible second-order nonlinear integrated photonic\nplatform.\n
