![]() Over the years, researchers have optimized the basic beam splitting devices for many times through the application of special structural design and optimization algorithm, and realized beam splitting devices with rich functions, which laid the foundation for the construction of large-scale integrated optical systems. So far, with the support of electromagnetic theory, optical waveguide theory and coupled mode theory, researchers can design splitters with different functions according to different applications, including power splitters, polarization splitters, wavelength division multiplexers, mode multiplexers, etc. It is closely related to the efficient utilization of sources and low loss propogation. Among them, on-chip beam splitting is not only the key link of photon propagation, but also an important part of integrated devices such as Mach Zehnder interferometer (MZI) and microcavity. Typical integrated optical systems include generation, coupling, splitting, modulation, and detection of photons. This paper introduces their research status, including optimization design methods, functions and applications in large-scale quantum chips and optoelectronic hybrid integration, looking forward to providing a reference for the further research of beam splitting methods and the wide application of beam splitters in the frontier field in the future.Ĭompared with the optical system composed of traditional optical devices, the photonic integrated circuit composed of on-chip optical devices has the advantages of wide bandwidth, easy implementation of dense wavelength division multiplexing (WDM), compact structure, light weight, low energy consumption, high reliability, easy integration, and compatibility with traditional CMOS technology. This paper reviews the on-chip beam splitting methods in recent years, which are mainly divided into the following categories: y-branch, multimode interference coupling, directional coupling, and inverse design. It is widely used in power splitting, polarization separation, wavelength division multiplexing and other scenarios. ![]() ![]() As a basic and important link in on-chip photon propagation, beam splitting is of great significance for the efficient utilization of sources and the compact integration of optoelectronic devices. The construction of large-scale integrated photonic circuit cannot be separated from the important role played by silicon-based optoelectronic devices. ![]()
