On-chip OELGs operating at telecom wavelengths are highly desirable for integration with the growing possibilities offered by silicon-based optoelectronics. However, at present operations are limited to linear logic functions in the ultraviolet or visible range and high-performance OELGs for multiple logic functions are lacking. Here we integrate up to three silicon waveguides with black phosphorus for optoelectronic logic operations at 1.55 μm. We demonstrate linear (AND, OR, NOT, NAND, NOR) and nonlinear (XOR and XNOR) OELGs by programming optical inputs into the waveguides and reading out electronic signals. The devices exhibit a responsivity as high as 0.35 A W−1 and a 3 dB bandwidth of 230 MHz. The combination of a photovoltaic OR gate and a voltage-switchable AND gate enables two-layer composite logic computing in the form (A + B)C. We also demonstrate symbol recognition, edge extraction, image fusion and encryption/decryption performed by these OELGs.

However, SMLM is often hampered by limited temporal resolution and the fixed frame rate of the acquisition. Here we present a new approach to SMLM data acquisition and processing based on an affordable event-based sensor. This type of sensor reacts to changes in light intensity, rather than integrating photons during the exposure time of each frame. Each pixel works independently and returns a signal only when an intensity change is detected. Compared with video acquisition using traditional electron-multiplying charge-coupled device or scientific complementary metal–oxide–semiconductor cameras, the event-based sensor provides higher temporal resolution and throughput on the positions of blinking molecules. We demonstrate event-based SMLM super-resolution imaging on biological samples with spatial resolution on a par with the performance of electron-multiplying charge-coupled device or scientific complementary metal–oxide–semiconductor cameras, while registering only the on and off switching of blinking molecules. We use event-based SMLM to perform very dense single-molecule imaging, where frame-based cameras experience major limitations. Event-based sensors enable super-resolution single-molecule localization microscopy with comparable quality and resolution to traditional scientific cameras, while also overcoming the limitations of high-density imaging.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"17 12","pages":"1105-1113"},"PeriodicalIF":35.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71417710","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}

Although there have been tremendous strides in direct frequency comb spectroscopy, these approaches have been unable to record high-resolution spectra on the nanosecond-timescale characteristic of many physiochemical processes. Here we demonstrate a new approach to achieve optical frequency comb generation in which a pair of electro-optic combs is produced in the near-infrared regime and subsequently transferred with high mutual coherence and efficiency into the mid-infrared regime within a single optical parametric oscillator. The high power, mutual coherence and agile repetition rates of these combs, as well as the large mid-infrared absorption of many molecular species, enable fully resolved spectral transitions to be recorded in timescales as short as 20 ns. We have applied this approach to study the rapid dynamics occurring within a supersonic pulsed jet; however, we note that this method is widely applicable to fields such as chemical and quantum physics, atmospheric chemistry, combustion science and biology. A mid-infrared dual-comb system capable of nanosecond time-resolved spectral measurements is realized by using a singly resonant optical parametric oscillator that allows an efficient conversion of an input dual-comb pump at 1 µm into an idler dual comb in the mid-infrared regime.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 2","pages":"127-131"},"PeriodicalIF":35.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71417438","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, increasing the brightness of these sources requires progressively larger instruments, with the largest examples, such as the Linac Coherent Light Source at Stanford, being several kilometres long. It would be transformative if this scaling trend could be overcome so that compact, bright sources could be employed at universities, hospitals and industrial laboratories. Here we address this issue by rethinking the basic principles of radiation physics. At the core of our work is the introduction of quasiparticle-based light sources that rely on the collective and macroscopic motion of an ensemble of light-emitting charges to evolve and radiate in ways that would be unphysical for single charges. The underlying concept allows for temporal coherence and superradiance in new configurations, such as in plasma accelerators, providing radiation with intriguing properties and clear experimental signatures spanning nearly ten octaves in wavelength, from the terahertz to the extreme ultraviolet. The simplicity of the quasiparticle approach makes it suitable for experimental demonstrations at existing laser and accelerator facilities and also extends well beyond this case to other scenarios such as nonlinear optical configurations. A new conceptual approach to light generation involving an ensemble of light-emitting charges may result in more compact superradiant light sources.","PeriodicalId":18926,"journal":{"name":"Nature Photonics","volume":"18 1","pages":"39-45"},"PeriodicalIF":35.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50164562","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}

X-ray free-electron laser (XFEL) radiation from hard X-ray self-seeding (HXRSS) setups has been demonstrated in the past and offers the necessary peak flux properties. So far, these systems could not provide high repetition rates enabling a high average flux. We report the results for a cascaded HXRSS system installed at the European XFEL, currently the only operating high-repetition-rate hard X-ray XFEL facility worldwide. A high repetition rate, combined with HXRSS, allows the generation of millijoule-level pulses in the photon energy range of 6–14 keV with a bandwidth of around 1 eV (corresponding to about 1 mJ eV–1 peak spectral density) at the rate of ten trains per second, each train including hundreds of pulses arriving at a megahertz repetition rate. At 2.25 MHz repetition rate and photon energies in the 6–7 keV range, we observed and characterized the heat-load effects on the HXRSS crystals, substantially altering the spectra of subsequent X-ray pulses. We demonstrated that our cascaded self-seeding scheme reduces this detrimental effect to below the detection level. This opens up exciting new possibilities in a wide range of scientific fields employing ultrafast X-ray spectroscopy, scattering and imaging techniques. A cascaded hard X-ray self-seeding system is demonstrated at the European X-ray free-electron laser.

Here we employ Rydberg atoms that allow the wideband coupling of optical and microwave photons at room temperature with the use of a modest set-up. We present continuous-wave conversion of a 13.9 GHz field to a near-infrared optical signal using an ensemble of Rydberg atoms via a free-space six-wave mixing process designed to minimize noise interference from any nearby frequencies. The Rydberg photonic converter exhibits a conversion dynamic range of 57 dB and a wide conversion bandwidth of 16 MHz. Using photon counting, we demonstrate the readout of photons of free-space 300 K thermal background radiation at 1.59 nV cm−1 rad−1/2 s−1/2 (3.98 nV cm−1 Hz−1/2) with a sensitivity down to 3.8 K of noise-equivalent temperature, allowing us to observe Hanbury Brown and Twiss interference of microwave photons.
