However, light propagation is affected by aberrations and multiple scattering, which drastically degrade the image quality and limit the penetration depth. Multi-conjugate adaptive optics and time-gated matrix approaches have been developed to compensate for aberrations but the associated frame rate is extremely limited for three-dimensional imaging. Here we develop a multi-spectral matrix approach to solve these fundamental problems. On the basis of a sparse illumination scheme and an interferometric measurement of the reflected wave field at multiple wavelengths, the focusing process can be optimized in post-processing for any voxel by addressing independently each frequency component of the reflection matrix. A proof-of-concept experiment shows a three-dimensional image of an opaque human cornea over a 0.1 mm3 field of view at a 290 nm resolution and a 1 Hz frame rate. This work paves the way towards a fully digital microscope allowing real-time, in vivo, quantitative and deep inspection of tissues. Based on the acquisition of a multi-spectral reflection matrix at a high frame rate, a fully digital microscope overcomes aberrations and multiple scattering to provide a three-dimensional image of an ex vivo opaque cornea at a resolution of 0.29 μm and 0.5 μm in the transverse and axial directions, respectively.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 10","pages":"1097-1104"},"PeriodicalIF":32.3,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141992022","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 direct observation of such Floquet states, which often requires low-temperature, high-vacuum housing of the interrogated materials and low-energy infrared photons or microwaves as the driver, has been challenging. Here we report the observation of Floquet states in CdSe nanoplatelets, which are the colloidal analogue of quantum wells, under ambient conditions using femtosecond transient absorption. A sub-bandgap visible photon dresses a heavy-hole state (|hh1〉) to a Floquet state (|hh1 + ℏωL〉) that can hybridize with the first quantized electron state (|e1〉). This enables us to probe the Floquet state using a near-infrared photon through its transition to the second quantized electron state (|e2〉). Dephasing of the Floquet state into the real population of |e1〉 is also directly observed with a dephasing time of a few hundred femtoseconds, which is well reproduced by our density matrix simulations. Researchers demonstrate the ambient-condition observation of Floquet states in CdSe nanoplatelets, a colloidal analogue of quantum wells.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 10","pages":"1044-1051"},"PeriodicalIF":32.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141974152","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}

Embedding topological properties into the enantiosensitive optical response of chiral molecules could therefore enhance the efficiency and robustness of chiral optical discrimination. Here we achieve such a topological embedding by introducing the concept of chiral topological light—a light beam which displays chirality locally, with an azimuthal distribution of its handedness described globally by a topological charge. The topological charge is mapped onto the azimuthal intensity modulation of the non-linear optical response, where enantiosensitivity is encoded into its spatial rotation. The spatial rotation is robust against intensity fluctuations and imperfect local polarization states of the driving field. Our theoretical results show that chiral topological light enables detection of percentage-level enantiomeric excesses in randomly oriented mixtures of chiral molecules, opening a way to new, extremely sensitive and robust chiro-optical spectroscopies with attosecond time resolution. The concept of chiral topological light—a polychromatic light with chiral closed 3D polarization trajectories, space-varying with the azimuthal angle—is introduced and used for efficient sensing in chiral molecules, showcasing an example of successful application of topological concepts in optics.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 11","pages":"1155-1160"},"PeriodicalIF":32.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41566-024-01499-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141974153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

It is described by the quantum-mechanical Bose–Einstein statistic, which allows Bose–Einstein condensation at low temperatures and high particle densities. Photons, historically the first considered bosonic gas, were late to show this phenomenon, observed in rhodamine-filled microcavities and doped fibre cavities. These findings have raised the question of whether condensation is also common in other laser systems with potential technological applications. Here we show the Bose–Einstein condensation of photons in a broad-area vertical-cavity surface-emitting laser with a slight cavity-gain spectral detuning. We observed a Bose–Einstein condensate in the fundamental transversal optical mode at a critical phase-space density. The experimental results follow the equation of state for a two-dimensional gas of bosons in thermal equilibrium, although the extracted spectral temperatures were lower than the device’s. This is interpreted as originating from the driven-dissipative nature of the photon gas. In contrast, non-equilibrium lasing action is observed in the higher-order modes in more negatively detuned device. Our work opens the way for the potential exploration of superfluid physics of interacting photons mediated by semiconductor optical nonlinearities. It also shows great promise for enabling single-mode high-power emission from a large-aperture device. Bose–Einstein condensation of photons is demonstrated in a large-aperture electrically driven InGaAs vertical-cavity surface-emitting laser diode at room temperature. The observed photon Bose–Einstein condensate exhibits the fundamental transversal optical mode at a critical phase-space density.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 10","pages":"1090-1096"},"PeriodicalIF":32.3,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41566-024-01478-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141918855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Atoms, magnons, solid-state excitons, surface plasmon polaritons and excitons coupled to light exhibit BEC, which results in high coherence due to massive occupation of the respective system’s ground state. Surprisingly, photons were shown to exhibit BEC recently in organic-dye-filled optical microcavities, which—owing to the photon’s low mass—occurs at room temperature. Here we demonstrate that photons within an inorganic semiconductor microcavity also thermalize and undergo BEC. Although semiconductor lasers are understood to operate out of thermal equilibrium, we identify a region of good thermalization in our system where we can clearly distinguish laser action from BEC. Semiconductor microcavities are a robust system for exploring the physics and applications of quantum statistical photon condensates. In practical terms, photon BECs offer their critical behaviour at lower thresholds than lasers. Our study shows two further advantages: the lack of dark electronic states in inorganic semiconductors allows these BECs to be sustained continuously; and quantum wells offer stronger photon–photon scattering. We measure an unoptimized interaction parameter ( $$tilde{{{{{g}}}}}$$ ≳ 10–3), which is large enough to access the rich physics of interactions within BECs, such as superfluid light. Photon Bose–Einstein condensation is observed in a semiconductor laser, where thermalization and condensation of photons occur using an InGaAs quantum well and an open microcavity.

To address this challenge, we demonstrate an all-Si receiver (RX) based on a cost-efficient, eight-channel, double-microring-resonator, avalanche photodiode. It has an aggregate data rate of 1.28 Tb s−1.

Therefore, materials with strong optical anisotropy have been long-sought. Recently, two-dimensional van der Waals crystals show high optical anisotropy but are mostly restricted to the out-of-plane direction, which is challenging to access in optical engineering. Here we report a two-dimensional van der Waals material, NbOCl2, that exhibits sharp electronic and structural contrast between its in-plane orthogonal axes.
