“…Additionally, the rapid advancement of MDM technology enables power splitters supporting multiple modes to enhance the transmission and processing speed of high-capacity information greatly. Presently, common multimode power splitters include devices such as multimode interference couplers (MMI) [11,12] and directional couplers (DC) [9,13]. These couplers have limited-wavelength bandwidth support and require complex designs to achieve arbitrary power splitting ratios (PSRs), which significantly restricts their utility in on-chip MDM applications.…”

Mode division multiplexing (MDM) technology is an effective solution for high-capacity optical interconnection, and multimode power splitters, as essential components in MDM systems, have attracted widespread attention. However, supporting a wide range of modes and arbitrary power splitting ratios with large bandwidth in power splitters remains a significant challenge. In this paper, we designed a power splitter based on a subwavelength grating (SWG) structure with tilted placement on a silicon-on-insulator (SOI) substrate. We achieve arbitrary TE0–TE9 mode-insensitive power distribution by altering the filling coefficient of the SWG. Thanks to our specific selection of cladding materials and compensatory design for the optical wave transmission and reflection shifts induced by SWG, our device demonstrates low additional loss (EL < 1.1 dB) and inter-mode crosstalk (−18.8 < CT < −60 dB) for optical modes ranging from TE0 to TE9, covering a wavelength range from 1200 nm to 1700 nm. Furthermore, our proposed device can be easily extended to higher-order modes with little loss of device performance, offering significant potential in MDM platforms.

On‐chip optical polarizer can extract the desired polarized light signal while filtering out the other polarized light signal, which plays a key role in integrated photonic circuits for purifying the desired polarized signal and reducing polarization crosstalk. However, most of the reported optical polarizers can only work for fundamental modes. With the rapid development of on‐chip multimode processing systems, arbitrary high‐order mode optical polarizers are more desirable. In this contribution, a TM‐pass optical multimode polarizer is proposed and demonstrated using subwavelength grating‐based anisotropic manipulation, which can achieve the polarizing of arbitrary TM high‐order mode theoretically, and the experimental results show the lowest polarization extinction ratio of the fabricated device can reach up to 21.2 dB under working for four‐mode (TM0, TM1, TM2, and TM3) system. The dynamic data transmission with the data rate of 64 Gbit s−1 has also been demonstrated to verify its potential for systematized applications in the future.
