“…The measured distributions in Figures 8 and 9 closely resemble the distributions acquired by the simulations. Further details about the fabrication and NSOM measurements of the 1 × 4 MMI splitter are available in our previous work [33]. Characterisation of the modal distribution across the output part was carried out using a highly resolved near-field scanning optical microscope (NSOM).…”

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.

The paper shows concepts of optical splitting based on three dimensional (3D) optical splitters based on multimode interference principle. This paper is focused on the design, fabrication and characterization of 3D MMI splitter with formed output waveguides based on IP-Dip polymer for direct application on optical fiber. The MMI optical splitter was simulated and fabricated using direct laser writing process. Output characteristics were characterized by highly resolved near-field scanning optical microscope (NSOM) and compared with 3D MMI splitter without output waveguides.

“…Its straightforward design and enhanced stability make it a compelling option for various optical uses, from telecommunications to sensing and signal processing. Many studies have shown that Y-branch MMI splitters work well in various applications [15][16][17][18][19][20]. They're good at splitting signals, don't lose much signal, and are easy to make.…”

This research presents a novel strategy for enhancing optical network efficiency by implementing a taper-based single-mode step-index (SI) core polymer Y-branch multimode interference (MMI) splitter. The innovative splitter design offers notable benefits in terms of performance, cost-effectiveness, and scalability. By capitalizing on the inherent attributes of the polymer material, including its minimal propagation losses and flexibility, we meticulously engineer this Y-Branch MMI polymer splitter. A 5 μm core width is purposefully maintained in the input and output components to uphold single-mode conditions. Embracing the self-imaging principle, the design and optimization of this Y-branch splitter are conducted employing the beam propagation method at a 1.55 μm wavelength. SI MMI splitters achieve a commendable power splitting efficiency of 86%. Our examination shows an excess loss of 0.52 dB and 0.50 dB for TE and TM modes, respectively. Furthermore, the calculated polarization dependence loss (PDL) is 0.015 dB, with a propagation loss of only 0.00019 dB/μm.
