By demonstrating broadband laser absorption spectroscopy of the fundamental vibrational mode of molecules, the spectral range is determined and the spectroscopic potential of this laser is established. The frequency noise is characterized and the line width of this new device is measured, uncovering a discrepancy with the current consensus on the theoretical modeling of quantum cascade lasers. The results confirm the potential of such novel narrow‐line‐width sources for vibrational spectroscopy. Extending laser spectroscopy to longer wavelength is a fascinating prospect that paves the way for a wide range of opportunities from chemical detection, to frequency metrology as well as for exploring light‐matter interaction with an extended variety of molecules, from ultra‐cold diatomic species to increasingly complex molecular systems.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"11 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002818","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}

However, the unsatisfactory polarization extinction ratios (PERs), impaired responsivities, and low Stokes parameter measurement accuracy of monolithic full‐Stokes polarimeters pose significant challenges for practical applications. Here, a metasurface‐integrated quantum well infrared photodetector (meta‐QWIP) is presented for long‐wavelength infrared full‐Stokes polarimetry. Leveraging the dual polarization selection by the metasurface and the quantum wells, a high linear PER (432) and a high circular PER (21) are achieved. Moreover, the polarization‐converted and intensified local field increases the responsivity by tens of times. The metasurfaces are properly designed to configure the optoelectronic polarization eigenvectors of the 6 pixels for an optoelectronic conversion matrix (OCM) with a low condition number. By solving an inverse problem of the OCM, high‐accuracy full‐Stokes parameters reconstruction (RMSE below 1%) is achieved. The full‐Stokes polarimetric imaging using our device demonstrates its superiority in resolving targets. This work advances high‐performance monolithic LWIR full‐Stokes polarimeters.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"12 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145002821","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}

Further regulating the intrinsic properties of the structure enables a high polarization ratio in the near-infrared region, applicable to both linear polarization or circular polarization states.
