We describe the quantum detection analysis for Polarization Shift Keying (PolSK) modulation formats with laser coherent states, deriving their theoretical performance bounds in error probability and mutual information; and we propose a receiver structure based on a polarization-displacement technique, inspired on the conventional quadrature-displacement schemes employed in the reception of Phase Shift Keying (PSK) modulation formats. Experimentally, we implement our coherent states receiver in a polarization-nulling configuration, employing linear optics for the polarization rotations and displacement, with photon counting at the telecommunications wavelength of 1550 nm, and performing post-detection count–to–voltage operations and logical decision with optimized photon number thresholds; additionally, as a reference, we also implement a quadrature-nulling receiver for a binary PSK format. We perform measurements on the symbol error probability of our receiver, as a function of the photon number of the received photonic signal, finding good agreement with the theoretical estimation at low photon numbers. This receiving structure has advantages over the conventional polarization-splitting and separate photon counting schemes, which is of interest in quantum communications, quantum cryptography and other fields in quantum information.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 6","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08684-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147938703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One key factor of this strategy is the generation of the local oscillator in combination with the pump and Stokes pulses internally within a single light source. This mechanism allows for a high local oscillator power of more than 400 nW and a fixed phase relation of the local oscillator with respect to the pump and Stokes pulses. Another feature of the strategy is that the local oscillator adjusts automatically to the appropriate wavelength across the whole tuning range of the light source between 1300 and 3000 cm<sup>−1</sup>, allowing for a simple setup without the need for realignment. A further key factor is an active phase stabilization scheme, enabling long-term measurements over more than 1.5 h with interferometric stability without the need for realignment at different wavenumbers. A nonresonant CARS signal provides the reference for the stabilization. For verification, the setup is applied to hCARS microscopy with 5-fold image contrast improvement due to the suppression of nonresonant CARS signal.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 6","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08672-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147863144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selected configurations provide insights into particle size evolution, soot filaments topology, their probability of appearance, and soot volume fractions. Jet A-1 flame exhibits higher soot loads with longer decay times, indicating larger and more developed particles. In contrast, the Isopar flame shows weak soot signals with nearly constant decay times, suggesting limited particle growth. According to temporally averaged planar LII, significant differences are observed between both flames, in terms of intensity and spatial distribution. In the Isopar flame, apart from the lower observed signal, the spatial distribution is more homogeneous without a clear maximum, making it impossible to distinguish locations where soot formation or oxidation dominate. 2D LII soot filament intermittency is characterized using statistical image-to-image metrics to evaluate soot filaments topology between the two flames. Spectral measurements revealed the presence of interfering fluorescence and provided a means to infer the soot volume fraction in the Jet A-1 flame. These findings underscore the complexity of soot formation in spray flames and the need for multi-scale, time-resolved measurements to characterize these environments.</p></div>","PeriodicalId":474,"journal":{"name":"Applied Physics B","volume":"132 5","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00340-026-08655-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our previous studies, hBN-based heterostructures with these monolayers exhibited favorable band alignment and optoelectronic characteristics. In this work, we investigate the role of strain in shaping the structural and electronic behavior of hBN/GaS, hBN/GaSe, and hBN/InS heterostructures using first-principles DFT calculations.
