Emerging Innovations in Neuromorphic Computing

By Casimer DeCusatis | Posted: 28 October 2021

Research in photonic computing, particularly photonic integrated circuits, has been ongoing for some time; this includes recent applications in neuromorphic computing, the use of large-scale integrated hardware or software systems to mimic biological architectures in the human brain and nervous system. In this blog, we’ll take a quick look at some emerging innovations in this area.

Industry Advances in Quantum Technology

By Casimer DeCusatis | Posted: 2 September 2021

One of the most highly anticipated sessions at this year’s OFC conference was the symposium on quantum information science and technology in the context of optical communications. While quantum information science covers a broad range of topics including quantum sensors and computer algorithms, some of the most interesting presentations are from leading telecom providers worldwide related to the development of quantum communication systems. Photonics plays a major role in these systems, and holds great potential for next generation voice and data networks. This month, we’ll look at some of the exciting recent developments in this field.

Telcos and Vendors Agree: Automation Is Needed for Network Cost Reduction

By Guest blogger - Matt Walker, Chief Analyst, MTN Consulting | Posted: 9 June 2021

If you’re selling technology to communications operators and automation isn’t front and center in your messaging, then you aren’t reading the room right.

Automation is viewed as not only bringing cost savings, but also adding intelligence that humans alone cannot deliver. That applies to deploying and troubleshooting services; designing, building and operating networks; and, even back in the factory & lab setting.

800G Pluggable Optics Drive a New Approach to Test and Validation

By Guest blogger - Dr. Paul Brooks, High-Speed Optical Transport Strategy, VIAVI Solutions | Posted: 1 June 2021

The pluggable optic ecosystem has undergone a revolution in complexity over the past decade. Technology has evolved from 100G modules using analog clock and data recovery (CDR) circuits, Non-Return-to-Zero (NRZ) modulation and simple firmware, to complex digital signal processing (DSP)-based equalization and CDRs, Pulse Amplitude Modulation 4-level (PAM-4) modulation and advanced module management like content management interoperability services (CMIS).

Top Three Trends at the Network Edge

By Casimer DeCusatis | Posted: 31 May 2021

Many leading computer industry analysts have been predicting a surge in edge computing and networking applications for the coming year despite the recent pandemic. The concept of bringing vital services closer to the network edge is being driven by a need to improve available application bandwidth, reduce latency, improve resiliency, and provide better security. There are many possible use cases including telecom networks that require service provisioning closer to end users—internet of things (IoT) systems, machine learning, augmented reality and more.  Since modern enterprises can use centralized resources for compute-intensive workloads and edge resources for real time applications, this approach compliments the hybrid cloud model. These topics will be discussed at the OFC Symposium on MEC-based network architectures in support of enterprise cloud. In preparation for this event, let’s take a look at some of the major industry trends for edge networking and cloud computing.

High Purity Lasers Lead the Way to Quantum Computing

By Casimer DeCusatis | Posted: 26 April 2021

Quantum computing has received a lot of attention recently, with a wide range of possible applications ranging from the financial sector to the automotive industry and beyond. It’s only appropriate that discussions on quantum information science will take center stage at OFC 2021. While many near term quantum computers require superconducting materials or other extreme operating conditions, some architectures based on photonics may offer important advantages. In this blog, we’ll take a closer look at the optical science behind quantum computers, specifically the role of new laser technologies in creating the next generation of room temperature quantum systems.

Machine Learning for Optical Communications

By Casimer DeCusatis | Posted: 8 February 2021

Machine learning has received a lot of attention recently, as it finds applications in everything from self-driving cars and digital personal assistants to language translators and fraud detection systems. It’s apparent that while machine learning (and its cousin, artificial intelligence) can’t solve every problem, there are a set of well-defined issues that are very well suited to this approach.In this blog, we’ll consider what makes a good candidate problem for machine learning, and look at some of the emerging solutions in optical communication physical layer and transport networks.

The Million Qubit Challenge

By Casimer DeCusatis | Posted: 11 January 2021

Within the past few years, quantum computing has moved from the realm of the purely theoretical into the practical as the world’s first working quantum computers have been demonstrated. Currently, these computers are about as powerful as the early difference engines built out of metal gears and hand cranks by Charles Babbage. But if we can harness polarized photons for quantum calculations, there is enormous potential to scale these devices to much more powerful systems.

Quantum Information Science at OFC

By Casimer DeCusatis | Posted: 17 July 2020

As far back as the early 1980s, Richard Feynman suggested that quantum computers might offer significant advantages over classical computers in solving certain problems in physics and chemistry. More recently, we’ve come significantly closer to overcoming the many theoretical and experimental obstacles which make practical quantum computing so difficult.

Pandemics and Global Digitization: How It’s Affecting Optical Technology

By Casimer DeCusatis | Posted: 28 April 2020

As of this writing, the COVID-19 pandemic continues to spread with few signs of slowing down; over 2.2 million cases and over 150,000 deaths have been reported so far. Despite this, the OFC conference continued to serve as the preeminent technical exchange for optical communications and networking professionals, with many technical sessions now available for online viewing to those who registered for OFC. In fact, there are some industry analysts who feel that recent events might lead to significantly greater interest in optical communication technologies.
