We utilized a dataset of quantum emission signals ranging from 604 to 629 nm, emitted from WS₂ monolayer nanobubbles on gold substrates, categorized into four spectral bands (604.06–608.24 nm, 611.07–616.34 nm, 617.42–623.35 nm, and 624.16–636.57 nm). Our methodology involved signal preprocessing through normalization and moving average smoothing, followed by transformation into 128 × 128 RGB images using Continuous Wavelet Transform (CWT) with Complex Morlet wavelet. Three convolutional neural network architectures (ResNet50, VGG16, and Xception) were implemented and evaluated using fivefold cross-validation across six possible band pair combinations. All models demonstrated exceptional classification performance, with VGG16 achieving the highest overall mean accuracy of 99.4%, followed by Xception (99.1%) and ResNet50 (98.2%). Perfect classification accuracy (100%) was consistently achieved for spectrally distant band pairs, particularly Band 1 versus Band 4 (20.5 nm separation), while the most challenging classification involved adjacent bands (Band 2 vs. Band 3, 6.27 nm separation) with VGG16 achieving 96.5% accuracy. Statistical analysis using Friedman tests confirmed significant performance differences among models (χ\r\n                    <jats:sup>2</jats:sup>\r\n                     = 8.67,\r\n                    <jats:italic>p</jats:italic>\r\n                     = 0.013). Xception demonstrated remarkable computational efficiency, achieving optimal convergence in as few as 2 epochs for certain band combinations while maintaining ultralow training loss values (8.23 × 10⁻\r\n                    <jats:sup>6</jats:sup>\r\n                    ). Deep learning models, particularly when combined with CWT preprocessing, provide a robust framework for quantum emission signal classification with significant implications for quantum photonics, quantum cryptography, and quantum sensing applications. Our approach bridges the gap between classical machine learning and quantum materials characterization, establishing quantifiable metrics for evaluating spectral distinguishability in quantum information systems.

In this paper, we propose a novel distributed algorithm that enables a group of modules to reconfigure into a rhombus shape, starting from an arbitrary side-connected configuration. It is connectivity-preserving and operates under minimal assumptions: one leader module, common chirality, constant memory per module, and visibility and communication restricted to immediate neighbors. Unlike prior work, which relaxes the original sliding square move-set, our approach uses the unmodified move-set, addressing the additional challenge of handling locked configurations. Our algorithm is sequential in nature and operates with a worst-case time complexity of O(n^2) rounds, which is optimal for sequential algorithms. To improve runtime, we introduce two parallel variants of the algorithm. Both rely on a spanning tree data structure, allowing modules to make decisions based on local connectivity. Our experimental results show a significant speedup for the first variant, and a linear average runtime for the second variant, which is worst-case optimal for parallel algorithms."}],"doi":"10.1007/978-3-032-11127-2_26"},{"author":[{"id":"20792","last_name":"Scheideler","first_name":"Christian","full_name":"Scheideler, Christian"},{"first_name":"Andreas","full_name":"Padalkin, Andreas","last_name":"Padalkin","id":"88238"},{"last_name":"Kumar","first_name":"Manish","full_name":"Kumar, Manish"}],"title":"Reconfiguration and locomotion with joint movements in the amoebot model.

Future optical components must combine very high modulation bandwidths—supporting signaling at 100 Gbaud and 200 Gbaud—with reduced spectral width to mitigate chromatic-dispersion-induced pulse broadening and increased brightness to further restrict flux-confining area in multi-mode fibers and thereby increase the effective modal bandwidth (EMB). A particularly promising route to improved performance within standard oxide-confined VCSEL technology is the introduction of multiple isolated or optically coupled oxide-confined apertures, which we refer to collectively as multi-aperture (MA) VCSEL arrays. We show that properly designed MA VCSELs exhibit narrow emission spectra, narrow far-field profiles and extended intrinsic modulation bandwidths, enabling longer-reach data transmission over both multi-mode (MMF) and single-mode fibers (SMF). One approach uses optically isolated apertures with lateral dimensions of approximately 2–3 µm arranged with a pitch of 10–12 µm or less. Such devices demonstrate relaxation oscillation frequencies of around 30 GHz in continuous-wave operation and intrinsic modulation bandwidths approaching 50 GHz. Compared with a conventional single-aperture VCSELs of equivalent oxide-confined area, MA designs can reduce the spectral width (root mean square values &lt; 0.15 nm), lower series resistance (≈50 Ω) and limit junction overheating through more efficient multi-spot heat dissipation at the same total current. As each aperture lases in a single transverse mode, these devices exhibit narrow far-field patterns. In combination with well-defined spacing between emitting spots, they permit tailored restricted launch conditions in MMFs, enhancing effective modal bandwidth. In another MA approach, the apertures are optically coupled such that self-injection locking (SIL) leads to lasing in a single supermode. One may regard one of the supermodes as acting as a master mode controlling the other one. Streak-camera studies reveal post-pulse oscillations in the SIL regime at frequencies up to 100 GHz. MA VCSELs enable a favorable combination of wavelength chirp and chromatic dispersion, extending transmission distances over MMFs beyond those expected for zero-chirp sources and supporting transfer bandwidths up to 60 GHz over kilometer-length SMF links.</jats:p>","lang":"eng"}],"intvolume":"        12","volume":12,"_id":"61932","issue":"10","date_updated":"2026-02-19T12:39:12Z","article_number":"1037","publisher":"MDPI AG","date_created":"2025-10-23T10:59:59Z","publication":"Photonics","status":"public","language":[{"iso":"eng"}],"year":"2025","publication_identifier":{"issn":["2304-6732"]},"type":"journal_article"},{"author":[{"last_name":"Diiankova","full_name":"Diiankova, Uliana","first_name":"Uliana"},{"first_name":"Mariusz","full_name":"Drong, Mariusz","last_name":"Drong"},{"first_name":"Tobias","full_name":"Pusch, Tobias","last_name":"Pusch"},{"first_name":"Rainer","full_name":"Michalzik, Rainer","last_name":"Michalzik"},{"full_name":"Lindemann, Markus","first_name":"Markus","last_name":"Lindemann"},{"orcid":"0009-0002-5538-231X","full_name":"Gerhardt, Nils Christopher","first_name":"Nils Christopher","id":"115298","last_name":"Gerhardt"},{"first_name":"Martin R.","full_name":"Hofmann, Martin R.","last_name":"Hofmann"}],"intvolume":"        10","citation":{"apa":"Diiankova, U., Drong, M., Pusch, T., Michalzik, R., Lindemann, M., Gerhardt, N.

We experimentally demonstrate the existence of multi-resonant polarization dynamics when spin is injected, a phenomenon previously unobserved. The development opens the door to significantly faster and more efficient optical communication systems by harnessing the collective behavior of multiple laser modes.

State-of-the-art laterally coupled devices require non-standard manufacturing technology and precise tuning of the currents supplied to each cavity separately to form optical supermodes suitable for such resonances. Here, we report on a novel switching phenomenon in laterally coupled VCSEL structures having only a single common electric contact and manufactured in a standard oxide-confined VCSEL geometry. At lower currents, they can be operated in a weakly coupled (WCR) regime and, at higher currents, in an injection-locked (IL) regime, enabling fundamentally different spectral and dynamic features. In the WCR, both optical supermodes lase and a narrow tunable plasma-assisted peak at their beating frequency is observed for each of the apertures, with a current-dependent frequency tuning and anti-phase intensity oscillations in each of the cavities. In contrast, in the IL regimes, only one (anti-symmetric) supermode lases. This adds a broader resonance to the modulation response while the intensity oscillations in both cavities are in-phase. Only the IL regime can result in increased modulation bandwidth of the system. Measurements of the pulse responses and continuous modulation up to 70 GHz for both operational regimes are presented and compared with simulations of our distributed rate equation model whose parameters are extracted from full-wave electromagnetic simulations of the device, including the temperature distribution in the device. Excellent agreement is found and enables comprehensive understanding of the dynamics of supermodes in oxide-confined coupled cavity VCSELs.</jats:p>"}],"title":"Laterally coupled vertical-cavity surface-emitting lasers with                    tunable resonance width and frequency","author":[{"last_name":"Lindemann","full_name":"Lindemann, M.","first_name":"M."},{"full_name":"D’Alessandro, M.","first_name":"M.","last_name":"D’Alessandro"},{"full_name":"Ledentsov, N.","first_name":"N.","last_name":"Ledentsov"},{"last_name":"Makarov","full_name":"Makarov, O.
