Here, we introduce a multi-wavelength achromatic imaging system utilizing a pleochroic confocal photon sieve (PCPS). In this technique, three foci at three different wavelengths are designed to coexist at various spatial locations on the same plane.

Furthermore, we also explored the potential application of the PCPS in single-frame multi-wavelength coherent diffraction imaging (CDI), and preliminary experimental results are presented to confirm the effectiveness of the proposed method. The proposed PCPS exhibits a minimal thickness and demonstrates high design flexibility in focal length and incident wavelengths, providing new opportunities for the development of achromatic imaging systems and RGB holographic displays.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":"37 5","pages":"285-288"},"PeriodicalIF":2.3,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our splitter leverages the direct binary search algorithm to optimize the pixelated design space, ensuring symmetric and efficient power distribution across the eight output waveguides. This design achieves a notably small footprint, low insertion loss, and excellent uniformity performance at the communication wavelength of 1550 nm. To validate our approach, we fabricated a <inline-formula> <tex-math>$1times 8$ </tex-math></inline-formula> power splitter on a silicon-on-insulator (SOI) platform, featuring ultra-compact length and space of just <inline-formula> <tex-math>$5.33~mu $ </tex-math></inline-formula>m and <inline-formula> <tex-math>$56.12~mu $ </tex-math></inline-formula>m2 respectively. This size represents a reduction of 1-2 orders of magnitude compared to previously reported values. Experimental results reveal an impressive insertion loss of 0.66 dB and a good uniformity of 0.42 dB at the center wavelength. Furthermore, the total loss remains below 1 dB across a wavelength range spanning from 1542.2 nm to 1553.5 nm. When compared to existing solutions, our designed splitter demonstrates superior performance in terms of size, insertion loss and uniformity.

The HMSIPF consists of a half-mode substrate integrated waveguide (HMSIW) with a periodic square spiral array etching onto the top metal layer. Additionally, two C-ring resonators are etched on both the top and bottom metal layers to introduce an extra transmission zero, enabling a sharp lower roll-off in the filter response without increasing its physical size. A prototype of the HMSIPF was fabricated and evaluated against comparable filters. Measured results demonstrate that the HMSIPF achieves a high transmission coefficient (|S21| > −0.8 dB) and a low reflection coefficient (|S11| < −12 dB) across a wide passband of 5.0-9.0 GHz, corresponding to a fractional bandwidth (FBW) of 57.1%.
