“…Nowadays, several classical structures used for on-chip beam splitting mainly include y-branch waveguide [35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51], splitters based on multimode interference (MMI) coupling [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69], splitters based on directional coupling (DC) [70][71][72][73][74][75], and splitters based on inverse design [76][77][78][79][80][81]. Among them, the design principle of y-branch waveguide is relatively simple, and the separation of mode and power is mainly realized through the y-type structure design.…”

The construction of large-scale integrated photonic circuit cannot be separated from the important role played by silicon-based optoelectronic devices. 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. It is widely used in power splitting, polarization separation, wavelength division multiplexing and other scenarios. 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. 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.

“…Both examples were fabricated using the Nanoscribe DLW system. This paper presents a design of 3D MMI polymer-based power splitters for direct attachment to fibre-tip using a supporting structure based on the previous work of Mizera et al [29]. The splitters were designed for an operating wavelength of 1550 nm.…”

Planar MMI couplers based on inorganic material platforms have played an essential role in photonic integrated circuits development. Advances in organic polymer fabrication techniques enable the design of components beyond a single plane, thus facilitating vertical integration for a wide range of components, including the MMI coupler. This paper presents the design of two 3D IP-dip polymer-based MMI power splitters operating in the near-infrared part of the spectrum at a wavelength of 1550 nm. The resulting output power ratio, modal field distributions, spectral characteristics, and the effects of input fibre misalignment are investigated using the beam propagation method. The fabrication method used to realise the designed splitters was direct laser writing. The function of the splitters was then verified by a highly resolved near-field scanning optical microscope.
