“…B23K) and material analysis (G01N; Kiefer et al, 2018;Yilbas et al, 2017). As for semiconductor lasers, they are more commonly used in optical fiber communications and optical storage (Gong et al, 2018). In the early twenty-first century, the size of the resonator has been reduced from micrometer to nanometer; semiconductor laser components of nanometer size possess characteristics, such as smaller occupying area and low power dissipation.…”

Purpose The application of laser and optical technologies in the industry is wide and extensive; the development and application of laser and optical technologies have become a promising research domain. However, most existing studies have focused on the technical aspects or the application aspects; these studies have not highlighted the technology distribution and application development of laser and optical technologies from the big picture. Additionally, the manner in which the research and development (R&D) results of universities correspond to the needs of enterprises and industry has become a topic of concern for the public. Therefore, this study aims to adopt the academic patents as the basis for analysis and to construct a laser and optical technology network. Design/methodology/approach Therefore, in the current study, the researchers have analyzed relevant academic patent technology networks, using academic patents of laser and optical technologies as a basis of analysis. Findings The study results indicated that the key technologies mainly lie in nanostructures, metal-working, material analysis and semiconductor devices. Additionally, these technologies are mainly applied in industries, such as optics, medical technology, pharmaceuticals, biotechnology and organic fine chemistry; this indicated that a large proportion of academia’s R&D outcomes are applied in these industries. Originality/value In this study, the researchers have constructed a technology network model to explore the technical development direction of laser and optical technologies; the results of the current study could serve as a reference for universities and industry for allocation of R&D resources.

“…Now, we introduce the self-imaging principle [27] as follows: "self-imaging is a typical property of multimode waveguides by which an input field profile is reproduced in single or multiple images at periodic intervals along the propagation direction of the waveguides". In particular, the polymer MMI splitters split the optical field based on the self-imaging principle with exciting a large number of modes, and the splitters exhibit the input field in one or more images at regular intervals along the propagation direction of the waveguides [28]. This phenomenon happens due to constructive interference between the higher modes (superposition of the modes with different propagation speeds), which appears inside the multimodal waveguides.…”

“…The MMI splitter demonstrates a distinctive intrinsic connection between the propagation constants (PC) of various modes, resulting in the achievement of self-imaging characteristics [22] as input signals propagate through multimode waveguides. The polymer MMI splitters utilize this principle to divide the optical field by inducing the excitation of multiple modes [23]. These devices lead the input field to appear as single or more images, spaced at regular intervals with the waveguide's propagation direction.…”

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.
