Here, we make an important step towards miniaturizing functional components on this platform, reporting high-speed LN electro-optic modulators, based upon photonic crystal nanobeam resonators. The flexible electro-optic modulation shown here may offer a convenient method for controlling the spectrotemporal properties of photons inside the cavity and for creating exotic quantum states48 that are crucial for quantum photonic applications. volume562,pages 101104 (2018)Cite this article.

Recently, there have been significant advance in high-Q LN photonic-crystal nanoresonators43,44,45,46, which led to the demonstration of intriguing phenomena and functionalities such as photorefraction quenching43, harmonic generation44, piezo-optomechanics45, and all-optical resonance tuning46. Wafer-scale heterogeneous integration of thin film lithium niobate on Integrated lithium niobate photonics is a promising platform for the development of high-performance chip-scale optical systems, but getting a laser onto a lithium niobate chip has proved to be one of the biggest design challenges, saidMarko Loncar, the Tiantsai Lin Professor of Electrical Engineering and Applied Physics at SEAS and senior author of the study. Reference [18] has recently emerged as a promising approach to realize integrated EO modulators with stronger optical connement and high EO efciencies while occupying a smaller footprint [4], [19]-[22].
