The technology works by utilizing photon energy to break Cooper pairs in superconducting nanowires, causing a local superconducting-to-non-superconducting phase transition. SNSPDs outperform traditional semiconductor devices, particularly in the near-infrared band, and have been widely validated in fields such as quantum information. This report provides a comprehensive overview of the global SNSPD market, covering capacity, output, revenue, and pricing. It includes analysis of market trends from 2019 to 2024, estimates for 2024, and projections for the compound annual growth rate (CAGR) through 2030. *𝗕𝘆 𝗧𝘆𝗽𝗲: Detection Efficiency ≥70%, Detection Efficiency ≥80%, Other *𝗕𝘆 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻: Quantum Information, Low Light Detection, Other *𝗕𝘆 𝗥𝗲𝗴𝗶𝗼𝗻: North America, Europe, Asia-Pacific, South America, Middle East & Africa *𝗕𝘆 𝗞𝗲𝘆 𝗣𝗹𝗮𝘆𝗲𝗿𝘀: Single Quantum, ID Quantique, Pixel Photonics, Photon Technology International, Inc. #SNSPD #SuperconductingNanowires #PhotonDetection #QuantumTechnology #SinglePhotonDetection #QuantumInformation #NanowireDetectors #SuperconductingPhaseTransition #CooperPairBreaking #NearInfraredDetection #PhotonSensors #QuantumOptics #HighPerformanceDetectors #SinglePhotonCounting #QuantumCommunication #SuperconductingElectronics #Photonics #LowTemperatureDetectors #PhotonDetectionSystems #QuantumPhotodetectors

It would be a nice dream to move from 200 to 300mm wafers at some point in the future, especially when and if large volume application markets start to develop. But, speaking for PICs, we see a technical diversity of chip manufacturing needs from many different SMEs in many different markets, which are at best of medium volume scale. Let’s prioritize efforts and resources in the creation of smart industrial value chains that can serve this diversity. I like to call that Silicon Photonics 4.0. Doing that with 200mm capacity will be hard enough for the foreseeable future.

📢 Photonics21 publishes white paper on 300mm Photonics. It explains that the time is right for some European photonics technologies to transition to larger wafers. Otherwise, Europe’s industry could be left behind.   📰 The paper was authored by a Photonics21 focus group of experts from RTOs, SMEs and industry, and is endorsed by AENEAS Association. It looks at three photonic technologies which are ready for the move from 200mm to 300mm wafers: thermal infrared imagers, photonic integrated circuits (PICs), and the 300mm tools needed for these.   By the end of 2029, these technologies have 𝗮 𝗽𝗼𝘁𝗲𝗻𝘁𝗶𝗮𝗹 𝗺𝗮𝗿𝗸𝗲𝘁 𝗼𝗳 €𝟭.𝟴𝗯𝗶𝗹 𝗮𝗻𝗱 𝟳𝟯𝟬𝟬 𝗱𝗶𝗿𝗲𝗰𝘁 𝗘𝘂𝗿𝗼𝗽𝗲𝗮𝗻 𝗷𝗼𝗯𝘀. And with the global move to 300mm already underway, Europe’s 𝘀𝗼𝘃𝗲𝗿𝗲𝗶𝗴𝗻𝘁𝘆 𝗶𝗻 𝗱𝘂𝗮𝗹 𝘂𝘀𝗲 𝗮𝗻𝗱 𝗰𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝘁𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 would be at risk if it does not transition too. These transitions will require substantial R&D and semiconductor tools investments to be successful.   👉 Read the news and download the white paper on our website: https://lnkd.in/eqKVH4Cw. #Photonics #Photonics21 #Innovation #Research #Wafers #WhitePaper

In the coming years, PICs and thermal imagers will see major surges in demand, both in terms of number of units and in terms of performance. 300 mm manufacturing lines will become necessary to address these needs. Considering that the cycle time of new semiconductor technologies can take as long as 5 to 10 years from development to product commercialization the transition from 200 mm to 300 mm wafers needs to be planned now.   Download the white paper to learn more.

Thrilled to announce that our article “Roles of temperature, materials, and domain inversion in high-performance, low-bias-drift thin film lithium niobate blue light modulators” has been published in Optics Express! https://lnkd.in/gwiz2Nae Modulators are essential components in optics that let us convert electrical information to optical. They’re critical for the internet data we access through fibers. A stable DC bias is needed for operating a modulator and transmitting information without errors. Bias drift is a common problem among such devices and has been circumvented by thermo-optic phase shifters, which consume orders of magnitude higher powers than electro-optic modulators. Making blue light modulators at GHz speeds is an entirely different (and exciting!) front for advancing neutral atom quantum computing and is more complicated than using telecom infrared light (1300-1600 nm), as blue photons (456 nm) have about 3x higher energy and tend to trigger additional physical mechanisms on-chip. Since the effects are much stronger, it turns out, it’s much easier to characterize them with blue light. In our paper, we investigate the effects of optical power and chip temperature on the switching voltage, test different electrode materials in terms of drift and I-V characteristics, and demonstrate a blue light modulator that is practically drift-free over more than 8 hours, without feedback or thermo-optic phase shifters. We also find that ferro-electric domain switching can be a substantial source of drift. #Optics #Photonics #TFLN #Optica
