Patent number: 11681099Abstract: The present invention provides a method for fabricating KTP nonlinear racetrack micro-ring resonator, composed of six steps: KTP wafer processing, ion implantation, electron beam exposure, subsequent processing, reactive ion etching and final processing. A thin-film waveguide structure similar to the on-insulator lithium niobate thin-film can be achieved through only one process of ion implantation, which enables significantly simplified procedure, shortened time, and reduced cost. Meanwhile, the KTP micro-ring resonator produced according to the present invention has an optical damage threshold several times higher than the existing lithium niobate micro-ring resonator. It can output nonlinear frequency converted light to the power of milliwatts, and suitable for the case where both the input and output optical signals are pulsed lasers.Type: GrantFiled: September 19, 2022Date of Patent: June 20, 2023Assignee: SHANDONG NORMAL UNIVERSITYInventors: Chen Chen, Zhanghua Han
