However, conventional SNAP microcavity shapes, such as parabolic and Gaussian curves, demonstrate limitations in handling noise interference from external environments, compromising displacement sensing accuracy. In this study, we propose a robust displacement sensing approach based on the bat-shaped SNAP microcavity. This unique profile supports a uniform first-order axial field mode. By utilizing the first-order axial mode as a reference, we apply Resonance Spectra Normalization (RSN) to standardize the resonance spectrum, reducing the impact of external perturbations. Extensive simulations validate the effectiveness of this technique. When coupling parameters deviate by up to 8%, our sensing method achieves a prediction error confined within a 4 μm range, compared to 14 μm in conventional displacement sensing solutions. This advancement enhances the sensor’s immunity to environmental noise, potentially revolutionizing microcavity displacement sensing, particularly in challenging environments beyond controlled cleanrooms.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"131 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143107927","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}

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.

The mature finite element tool is employed to conduct optical property analysis for the proposed all-fiber filter. The simulation results show that with reasonable design of structural parameters, the central operating wavelength of this filter can be determined at the common communication window of 1.55 μm. 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. Furthermore, the filter shows outstanding anti-bending capacity on the central wavelength and a high quadratic fitting relationship of 0.9938 between the bending radius and the central CT intensity. Additionally, it also has high manufacture feasibility.

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}
