This paper presents an effective compensation strategy to address this issue. A laser heat-mode lithography system is established with a tightly focused objective lens and a grid scanning strategy, achieving a minimum grid size of 6 nm. The factors affecting alignment accuracy are then analyzed from the perspectives of the positioning error, galvanometer scanning distortion and coordinate system inclination. Following this, a compensation strategy is proposed, which adjusts the coordinate system of the dual-galvanometer to compensate alignment error. Experiments demonstrate the effectiveness, significantly reducing the maximum alignment error from 92.4 nm to 8.4 nm, improving alignment accuracy by approximately 91%. Furthermore, the fabrication of various structures with a minimum linewidth of 150 nm further confirms the excellent alignment performance of the system and demonstrates the advantages of laser heat-mode lithography. This work provides flexible compensation strategies for improving alignment accuracy in the dual-galvanometer laser scanning lithography system, paving the way for advancements in systems based on direct laser writing or other step-stitching lithography techniques.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143107848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

When the Al wires are stimulated, the plasmonic mode and the y-polarized transmission mode satisfy the phase matching conditions, leading to the surface plasmon resonance (SPR) effect, a significant energy difference can be acquired in the x- and y-polarized directions at 1.55 μm. The 14 mm-long optical filter demonstrates a maximum crosstalk (CT) of 123.24 dB, and a wide bandwidth with CT greater than 20 dB of 410 nm, ranging from 1.39 μm to 1.80 μm.

Within the realm of infrared detection, it serves to enhance the detection of faint targets against complex backgrounds. Consequently, enhancing the performance of polarization devices has become one of the pivotal directions in quantum well infrared photodetectors (QWIPs) research. This paper proposes a novel circular polarization QWIPs inspired by stomatopods compound eye structure. By emulating the compound eye structure of the mantis shrimp, we integrate a top dielectric metasurface and a bottom one-dimensional metallic grating on QWIPs to achieve circular polarization detection. The dielectric metasurface, fabricated by etching heavily doped GaAs material, primarily functions as a quarter-wave plate, decomposing incident circularly polarized light into two orthogonally polarized linear components. The one-dimensional metallic grating at the bottom of device, acting as a linear polarizer, selectively excites surface plasmon polariton (SPP) modes, thereby distinguishing left-handed circularly polarized (LCP) light from right-handed circularly polarized (RCP) light. Finite-difference time-domain method was employed to calculate the total absorption spectrum of this integrated device. Under the LCP light incidence, the device exhibits a total absorption of 0.9 at the peak response wavelength of 7.8 μm, with a coupling efficiency of 3553%. Conversely, under RCP light incidence, the device demonstrates a total absorption of 0.1 at the same peak response wavelength, achieving a coupling efficiency of 95%. Furthermore, the device’s circular polarization extinction ratio reaches 37.4. This structure, achievable through quantum well focal plane array technology, represents a positive performing design for circular polarization QWIPs, contributing to enhancing target identification capabilities.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
