However, conventional spatial‐stacking designs struggle to simultaneously achieve minimalism and athermalization. Here, a minimalist meta‐composite optical architecture is proposed based on a full‐field inverse‐design method. By integrating two‐dimensional subwavelength meta‐atoms onto micro‐curved surfaces, this approach precisely regulates the thermal phase response, achieving significant suppression of both thermal and high‐order aberrations. Based on this, we further demonstrate a meta‐composite optical system (MCOS) comprising only two elements, achieving a focal shift of merely ±6.7 µm across the 8–12 µm bandwidth and a 100°C temperature span (from −40°C to 60°C). Meanwhile, the MCOS exhibits a superior modulation transfer function (MTF) and excellent imaging resolution under various temperature conditions. In addition, the athermalization mechanism and the tolerances of non‐ideal structural profiles for meta‐atoms are rigorously derived and analyzed, effectively mitigating temperature‐induced degradation of image quality. By integrating with an unmanned aerial vehicle (UAV) platform, the excellent infrared thermal imaging demonstration of the MCOS has been experimentally confirmed. This work offers a feasible pathway for the development of integrated optics and the deployment of minimalist optical systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"11 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 laser was split into a gas‐interacting signal arm carrying refractive‐index‐induced phase information and an acousto‐optic‐modulator (AOM)‐frequency‐shifted reference arm. After recombination, the two beams generated a photodetected heterodyne interference signal carrying the refractive‐index‐induced phase information. A 32.7 kHz QTF was used as a narrow‐band physical filter to suppress DC background and low‐frequency drift, concentrating the response near resonance. For phase readout, the AOM reference and QTF output were synchronously acquired to construct Hilbert analytic signals. Multiplying the detection‐channel analytic signal by the complex conjugate of the reference‐channel signal yielded a reference‐compensated instantaneous phase difference, converting absolute phase readout into relative phase readout and reducing offsets from system restart, acquisition‐trigger variations, and reference phase‐zero drift. Using C <jats:sub>2</jats:sub> H <jats:sub>2</jats:sub> as the target gas, the system achieves stable 2000 s measurement at 1%. Allan analysis shows 8.5 ppm sensitivity at 1 s and an optimized detection limit of 793 ppb at 53 s.

These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies. Here, an effective Hamiltonian approach is proposed to analyze the complex eigenvalues of scattering systems. By imposing zero scattering constraints (i.e., transmission or reflection zeros) on the Hamiltonian of a two‐mode photonic system, the complex eigenvalues corresponding to transmissionless and reflectionless modes are calculated and it is revealed that the Kerker anomalies are a result of spontaneous parity‐time (PT)‐symmetry‐breaking in the complex plane. This formalism provides a generic method to study non‐Hermitian scattering and offers physical insights into coupled‐mode resonating systems. Furthermore, it provides universal rules for designing photonic devices with unidirectional scattering and full 2π phase modulation.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"52 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
