NTT Research, a division of NTT, announced plans to double the size of its optical research facility in 2023. The expansion will accommodate the experimental needs of scientists in its Physics & Informatics (PHI) Lab who are studying Coherent Ising Machines (CIMs), which are networks of optical parametric oscillators (OPOs) programmed to solve problems mapped to an Ising model. The Ising model is a mathematical abstraction of magnetic systems composed of competitively interacting spins, or angular momenta of fundamental particles. NTT Research to Expand Optics Facility for Coherent Ising Machines Study in 2023 (gophotonics.com)

As a division of parent company NTT, NTT Research, Inc. is able to proffer its own news stream and announcements. This month sees the firm announce plans to double the size of its optical research facility in 2023. The announcement was made to journalists and data analysts at NTT Upgrade 2023, the organization’s technical user, customer and partner conference held this March in San Francisco.

NTT Research is of course a division of NTT and the Upgrade 2023 NTT Research Summit is in-person event on March 15-16, 2023 – and the event itself takes place at the NTT Experience Center (XC) and the Metreon, both in San Francisco. Day 1 will focus on the Innovative Optical and Wireless Network (IOWN) initiative. Day 2 will feature sessions on breakthroughs in data privacy, precision cardiology, nonlinear optics, advanced encryption technologies, the digital workplace and the network edge. What to expect from NTT Research ‘Upgrade’ 2023 (computerweekly.com)

NTT has developed a prototype chip that could increase communications speeds in data centers and submarine cables. The chip can amplify a 100 Gigahertz (GHz) electrical signal in laboratory conditions, a key step towards 6G. The ultra-compact baseband amplifier IC module is years away from being commercially released, but NTT expects to use the chip in future all-photonics networks. NTT believes that its core optical network, Innovative Optical and Wireless Network (IOWN), will require transmission speeds of more than two terabits per second and a baseband amplifier IC module that can amplify the signal.

NTT Corporation has succeeded in developing an ultra-compact baseband amplifier IC module with an ultra-broadband performance of 100GHz. This technology is expected to be used in future all-photonics networks, namely IOWN and 6G, and fields achieving cutting-edge measurements since they will require an ultra-broadband signal amplification function rid of distortion. To achieve this breakthrough, NTT applied its InP-based hetero junction bipolar transistor (InP HBT) technology to improve the performance of amplifier ICs and package mounting technology to incorporate a DC block function2 with 100 GHz bandwidth performance, realizing the world’s first ultra-compact amplifier IC module.

Japanese telecommunications giant Nippon Telegraph and Telephone Corp. today announced it has developed a prototype chip that it believes will one day be able to deliver a significant boost in data transfer speeds within data centers and undersea fiber optic cables. The company said its extremely compact new baseband amplifier integrated circuit module boasts an ultra-broadband performance of 100 gigahertz and is designed to be used with future all-photonics network technologies, including the nascent Innovative Optical and Wireless Network infrastructure and 6G networks. It’s a key element of those future networks, NTT says, because they will require ultra-broadband signal amplification functionality to eliminate distortion.

Japanese telecommunications NTT on Thursday unveiled a prototype chip that it believes will help boost communications speed in data centers and across undersea fiber optic cables in the future. While the technology’s release is still years out, the tiny chip would amplify a 100 Gigahertz (GHz) electrical signal, said Kazuhiro Gomi president and CEO at NTT Research, Inc. in Silicon Valley. NTT said its development will speed up the Internet for consumers and accelerate communication for data centers in the future.
