Title: Integrated photonics based on thin-film lithium niobate-chalcogenide hybrid waveguides Abstract: The thin-film lithium niobate (TFLN)-chalcogenide (ChG) hybrid waveguides as a novel device platform provide excellent optical and acoustic properties for the development of integrated acousto-optic interaction devices and nonlinear photonics. In our work, based on a nonsuspended TFLN-ChG hybrid Mach-Zehnder interferometer, we firstly proposed and demonstrated a built-in push-pull acousto-optic modulator (AOM) with a half-wave-voltage-length product as low as 0.03 V•cm that presents a modulation efficiency comparable to that of a state-of-the-art suspended counterpart. In addition, a new strategy is proposed for efficient second harmonic generation (SHG) by loading the ChG film over the TFLN platform. We experimentally observed efficient SHG and sum frequency conversion with a conversion efficiency of 51.1%/W. Temperature tuning of the SHG wavelength is also demonstrated with a measured tuning slope of 0.18 nm/K. The introduction of the TFLN-ChG hybrid waveguide platform shows huge opportunities for the advance of the high-performance integrated photonics.

Introduction

The formation of the Physical Society of Hong Kong (PSHK) was first motivated in Feb 1966 by a group of physicists from two universities at that time (that is, the Chinese University of Hong Kong and the University of Hong Kong) and from industries in Hong Kong. A preparation committee was formed, and in September 1966, the Society was formally constituted. Officers and Council members were also elected for a one-year period. In Nov 1966, the Hong Kong Government officially approved the Constitution of PSHK. At the present time, we have over 100 members from all six physics departments in the local universities. The Society is a member of the Association of Asia Pacific Physical Societies (AAPPS). Moreover, members of PSHK also receive reciprocal membership from several other physical societies. Currently, the executive committee of the PSHK consists of the President, Vice-President, Hon. Secretary, and Hon. Treasurer. The Council consists of 18 members coming from all 6 physics departments in Hong Kong.
