NTT develops world’s fastest directly modulated laser

 Researchers at NTT have developed the world's fastest directly modulated laser with a 3-dB bandwidth exceeding 100 GHz and capable of transmitting at 256 Gbps over a distance of 2 km.

The research was carried out in collaboration with Professor Fumio Koyama at the Laboratory for Future Interdisciplinary Research of Science and Technology, Tokyo Institute of Technology.


NTT researchers developed a membrane laser on a silicon (Si) substrate with a thermal oxide film (SiO2). The company says membrane lasers have a large optical confinement factor in the active region and are compact, making it possible to realize directly modulated lasers with low power consumption. On the other hand, since the device is fabricated on a low-thermal-conductivity SiO2 layer, the temperature increase in the active layer due to current injection is large, and even if the current is increased, the relaxation oscillation frequency saturates at about 20 GHz due to saturation of the differential gain.

To suppress the increase in the active region temperature, we fabricated an indium-phosphorus (InP) based membrane laser on a silicon carbide (SiC) substrate (Fig. 3), which has a thermal conductivity approximately 500 times higher than that of SiO2. Since SiC has a lower refractive index than InP, the optical confinement factor is almost the same as that of the device on SiO2. The device was fabricated by direct bonding with ultrathin (40 nanometers) SiO2 between the InP and SiC substrate. 

Assuming a 100-mW heat source, the temperature increase in the active region of a membrane laser with an active layer length of 50 micrometers was significantly reduced from 130.9 to 16.8℃ when the SiO2 thickness was reduced from 2 micrometers to 40 nanometers.

NTT develops its edge computing machine learning

NTT is developing an asynchronous distributed deep learning technology based on machine learning at the network edge.

NTT's research is focused on a training algorithm to create a global model of IoT data that is processed and stored at the edge.

NTT says its proposed technology, which has both academic and practical interest, enables to obtain a global model (a trained model that uses all the data at a single place) even when (1) statistically nonhomogeneous data subsets are placed on multiple servers, and (2) the servers only asynchronously exchange variables related to the model.

Details will be presented this week at KDD 2020 (Knowledge Discovery and Data Mining), an international conference sponsored by the Association for Computing Machinery (ACM) (16.9% acceptance rate). We also published the code associated with our achievement on Github for verification of our method effectiveness.

NTT charts a roadmap to the future IOWN All-Photonics Network

NTT outlined a technology roadmap for its Innovative Optical and Wireless Network (IOWN) vision, which was first announced in May 2019.

IOWN has three technical elements: All Photonics Network, Digital Twin Computing, and Cognitive Foundation. The roadmap calls for four technical directions:

(1) Full-Stack Communication Acceleration (Layer 4/Layer 3 Acceleration: CY2021, Technology for massive optical/wireless capacity: CY2023)

In order to take full advantage of the large capacity of IOWN All-Photonics Network, NTT will develop a new accelerated Layer 4/Layer 3 communication method that is less subject to the distance-related throughput degradation than TCP/IP. As the new communication method will lead to the explosive growth of data traffic, we will also develop a new network architecture and technology for massive optical and wireless capacity.

(2) Data-Centric Communication and Computing (CY2021)

NTT will develop Cognitive Foundation Data Hub (CF Data Hub), which enables nodes (sensor nodes or AI analysis nodes) to instantly exchange or share large data objects. By leveraging CF Data Hub as a central exchange point that faces multiple types of networks and computing infrastructures, IT infrastructures will shift from the conventional IP-centric paradigm to a new data-centric paradigm.

(3) Computing Scaling Across Device, Edge, and Center Cloud (CY2021)

NTT will develop a high-speed distributed computing technology that leverages ultra-broadband and low-latency communication on IOWN All-Photonics Network to realize a new cloud computing infrastructure that seamlessly spans multiple data centers.

(4) Sustainable Growth with Energy Efficiency (CY2023)

NTT will develop an architecture and technologies for photonic disaggregated computing, which significantly improves energy efficiency by replacing electronic data bus for inter-module data transfer with photonic data plane. After that, shift from electronic to photonic will also be applied to inter-package and inter-device interconnections on a step by step basis, which will eventually lead to a quantum leap improvement in energy efficiency.

NTT develops quantum light source for optical quantum computer chip

Researchers at NTT have developed a wide-band, high-performance quantum light source (squeezed light source) that could be used for optical quantum computer chips operating at room temperature.

The breakthrough finds that squeezed light has compressed quantum noise that can be used to create quantum entanglement. The light source can output continuous-wave wide-bandwidth high-level squeezed light. The light source can also increase the clock frequency of the quantum computer itself, setting a course for high-speed quantum computation.

NTT said the reserachers succeeded in compressing more than 75% of the quantum noise by using a high-performance nonlinear optical waveguide fabricated by NTT and a high-quality optical control and measurement technology of the University of Tokyo.

Looking ahead, the researchers aim to demonstrate the generation of large-scale entanglement states and various optical quantum operations for the realization of universal quantum computers using this wideband squeezed light.

A paper on this research will be published in “APL Photonics” on March 30, 2020.
