Evident Scientific, formerly Olympus Corp., has released version 4.1 of its SLIDEVIEW™ VS200 microscopy software. The update introduces a SILA optical sectioning device that utilizes speckle illumination and HiLo microscopy techniques to produce high-contrast and blur-free images. This new optical sectioning capability enhances image clarity and detail.

Additionally, the software incorporates TruAI™ technology, designed for precise segmentation of features within images, effectively distinguishing between similar-looking elements. TruAI also includes a selective scanning mode that significantly reduces data load by intelligently identifying and scanning only relevant sample areas, skipping regions of no interest. This feature optimizes data management processes, including storage, uploading, and image sharing for users.

The updated SLIDEVIEW™ VS200 software is designed to streamline workflows with features such as easy image uploading to a database, user access management, and tools for offline image visualization and annotation. The new version of the microscopy software is available as of May 2023.

Researchers have engineered a novel diffractive optical element capable of performing the fundamental NAND logic operation, paving the way for advanced all-optical computing systems. This innovative approach encodes binary information within the spatial distribution of light, specifically by using pairs of apertures where the relative optical power determines the logical state of ‘True’ or ‘False’.

Unlike previous methods that required additional energy-consuming probe lights and faced challenges in connecting multiple gates, this new design achieves cascadability. The output from one diffractive NAND gate can directly serve as the input for another, enabling the construction of complex optical circuits.

The team developed a four-layered diffractive neural network, trained through computer simulations, to execute the NAND function. They demonstrated the gate’s functionality by numerically testing it with various optical inputs, confirming its accurate operation.

Furthermore, the researchers showcased the practical application of this diffractive NAND gate by building essential logic gates such as AND, OR, and NOT. They achieved this by strategically cascading multiple NAND gates, mirroring the fundamental principles of digital electronic circuits but entirely in the optical domain. They also successfully constructed an all-optical half-adder, a basic arithmetic building block, using five cascaded diffractive NAND gates.

A key aspect of their findings highlighted the importance of a “design map” to navigate potential error points that arise when cascading these optical gates. By understanding these error combinations, it becomes possible to design more reliable and complex all-optical processors.

This development suggests a significant step forward in optical computing, potentially leading to faster and more energy-efficient information processing technologies by harnessing the speed and bandwidth of light.

AT&T has announced a significant advancement in network technology, demonstrating the readiness of its nationwide software-centric network to handle the escalating bandwidth demands driven by emerging technologies such as artificial intelligence, user-generated content, augmented and virtual reality, cloud computing, and streaming video.

The telecommunications company successfully tested a 1.6 terabit-per-second single-carrier wavelength across a 296-kilometer stretch of its commercial long-distance network. This groundbreaking speed is four times greater than the current 400Gb/s wavelengths. The test, an industry first, successfully carried two IEEE standards-based 800 Gigabit Ethernet end-to-end circuits, establishing a continuous data path using a single light frequency across the entire fiber length between two locations.

The trial was conducted on AT&T’s existing long-haul fiber network spanning from Newark, New Jersey, to Philadelphia, Pennsylvania, over a 296-kilometer route. Importantly, the 1.6 Tb/s wavelength was transmitted concurrently with existing live customer traffic running on 100Gb/s and 400Gb/s wavelengths.

For the network equipment, the trial utilized open-sourced white box switches. These switches, powered by the Broadcom Jericho3 packet processor chip, offer up to 18 x 800G network interface ports within a compact 2RU platform. The operation of these white boxes was managed by DriveNets Network Cloud software, a hardware-agnostic solution that employs open APIs to execute data and control plane functions, including routing at 800G.

Mike Satterlee, Vice President of Network Infrastructure and Services at AT&T, stated that the increasing use of connected devices by consumers is driving network traffic upwards. He anticipates a doubling of network traffic by 2028 and emphasized that the technologies validated in this trial are crucial for AT&T to meet growing customer demands for data transmission, video consumption, and streaming services.

Dino DiPerna, Senior Vice President of Global Research and Development at Ciena, highlighted that this achievement with AT&T builds upon Ciena’s history of industry firsts in optical network speed and capacity. He explained that Ciena’s WaveLogic 6 coherent optics will be instrumental in supporting AT&T’s next-generation converged optical network and its endeavors to create a cloud-based and AI-ready network characterized by increased scale, flexibility, and efficiency.

Pune-based optical fiber provider Sterlite Tech has announced a collaboration with the Telecom Infra Project (TIP) to develop an optical transport controller. This controller will be designed to manage and control the Voyager and Cassini transponders, which are open and disaggregated packet/optical transponders developed by members of TIP’s Open Optical and Packet Transport (OOPT) project.

Voyager, originally designed by Facebook and now evolving under Adva Optical with Cumulus Networks software, and Cassini, a white box transponder from Edgecore Networks, are key components of TIP’s OOPT initiative aimed at promoting open and disaggregated optical networks. Cassini integrates 100GbE switching with Layer-1 optical transport functions, suitable for data center interconnect, metro, and access backhaul applications.

Sterlite Tech’s contribution will be an open optical transport controller, along with a virtualized application for managing the data plane on these platforms. This controller will be contributed to the TIP community, furthering the collaborative nature of the project.

Ayush Sharma, Head of Programmable Networking and Intelligence at Sterlite Tech, emphasized the importance of optical networks as the foundation of operator transport infrastructure. He explained that while traditional vendor-specific solutions offer controller functions, they are typically proprietary. In contrast, an open optical transport controller becomes hardware agnostic, and open interfaces enable programmability. This approach allows telecommunications companies to select components from various vendors, as long as they adhere to open community standards, fostering greater flexibility and choice in building their networks.

TIP’s OOPT project aims to standardize packet optical interfaces and promote the adoption of disaggregated transport platforms by creating open DWDM solutions, models, and APIs for transponders, open line systems, and routers. This collaboration between Sterlite Tech and TIP is a step towards making optical transport networks more open and programmable.
