Optical computing has been a potential candidate for next-generation computing systems. Specifically, wavelength-division multiplexing (WDM) has been adopted in optical computing architecture to increase the computation bandwidth. Although existing WDM architectures have shown promise, they face challenges in the integration of light sources and further increase of the computing bandwidth. We introduce a mode-division multiplexing (MDM) strategy, offering what we believe to be a new degree of freedom in optical computing based on the micro-ring resonator platform. We propose an MDM approach and a multi-dimensional architecture that augments WDM with MDM to enhance channel capacity for computation. We design and experimentally demonstrate key components of the proposed architectures, including a multimode beam splitter, a thermo-optical tuner for the high-order mode, and a multimode waveguide bend. A proof-of-principle matrix multiplexing system, fabricated in a foundry and working for both MDM and MDM-WDM computing, is demonstrated.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 17","pages":"5498-5501"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the high computational costs of MC simulation limit its broader use in practice. Although GPU-accelerated MC methods significantly enhance computational efficiency, the time required remains substantial under conditions of high-photon numbers and fine mesh due to limited computational resources. Here, we developed a high-efficiency MC method based on the Fourier neural network (MC-Fourier) for high-speed computation of high-quality light fluence (LF) distributions from low-photon MC simulation results, enabling fast yet robust acquisition of two- and three-dimensional LF distributions on fine meshes (up to 10242). Tests conducted under different mesh configurations demonstrate that the MC-Fourier achieves comparable LF distribution quality to high-photon MC-GPU while reducing the number of photons used by three orders of magnitude. This strategy significantly reduces computation time without sacrificing fidelity, paving the way for fast biomedical optical imaging based on MC simulation.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 17","pages":"5302-5305"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, balancing the numerical aperture (NA), focusing efficiency, and spectral bandwidth remains a significant challenge in the existing PMMs, thus restricting their extensive applications. To circumvent these challenges, we theoretically demonstrate two unique orthogonal (linear and circular) PMMs based on all 4H-silicon carbide (4H-SiC) with superior NA, sound focusing efficiency, and broad wavelength range. This is achieved by judiciously engineering stacked rectangular 4H-SiC pillars based on either the propagation phase or geometric phase. The results show that the linear PMM (LPMM) works well (i.e., focusing efficiency > 60%, NA > 0.658) at wavelengths spanning from 800 nm to 925 nm, whereas the circular PMM (CPMM) achieves parallel performances over a bandwidth of 775 nm-900 nm. More particularly, both the PMMs can achieve excellent features with high NA of 0.7, focusing efficiency exceeding 75%, and sub-diffraction focal spot size of around 607 nm at the operating wavelength of 850 nm. As a proof-of-principle demonstration, the well-designed LPMM and CPMM can be further leveraged to get access to high-capability polarization imaging and encryption.","PeriodicalId":19540,"journal":{"name":"Optics letters","volume":"50 17","pages":"5474-5477"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144963743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
