The Nitride Technology Centre (NTC): Pioneering Sustainable AI with Light-Emitting Neuromorphic Computers

The Nitride Technology Centre (NTC), a groundbreaking microelectronics consortium spearheaded by Technische Universität Braunschweig, is leading the charge into a new era of computing innovation.

Supported by generous funding of €15 million from the state of Lower Saxony and the Volkswagen Foundation, the NTC’s ambitious initiative, known as “Bringing Light to Microelectronics” (BRIGHT), aims to revolutionize computing by developing a neuromorphic computer utilizing minuscule LEDs.

Scheduled to commence on April 1, 2026, the project is set to span five years, culminating in 2031.

Tackling AI Energy Consumption

A collaborative effort involving researchers from Technische Universität Braunschweig, Leibniz University Hannover, Ostfalia University of Applied Sciences, and the Physikalisch-Technische Bundesanstalt (PTB) is focused on addressing one of the most pressing challenges in modern technology: the escalating energy demands of AI systems.

According to the International Energy Agency (IEA), data centers could potentially consume 3% of global electricity by 2030, highlighting the urgent need for energy-efficient solutions to power the computational requirements of advanced neural networks.

Understanding Neuromorphic Computing

Distinct from traditional computers that rely on binary sequences for neural network simulations, neuromorphic computers directly embed these networks into hardware structures.

The NTC’s innovative strategy leverages tiny LEDs to replicate the interconnectedness of neurons within the human brain, enabling AI computations to occur simultaneously rather than sequentially, dramatically reducing energy consumption and enhancing processing efficiency.

Hybrid Technology: Bridging Light and Silicon

The BRIGHT project merges previously disparate technologies to optimize performance outcomes.

By integrating conventional silicon-based integrated circuits (CMOS) with light-emitting materials like gallium nitride, the NTC aims to create a hybrid neuromorphic computer that combines the reliability of silicon with the energy efficiency of light-emitting components.

This hybrid approach not only enhances performance but also introduces new possibilities for diverse microelectronics applications.

Angela Ittel, President of TU Braunschweig, lauded the BRIGHT project for its groundbreaking approach to sustainable AI, emphasizing the importance of scientific advancement in shaping a more energy-efficient future.

Progress and Future Endeavors

The LENA research center in Braunschweig has already validated the feasibility of LED-based neuromorphic computing.

Over the next five years, the BRIGHT team aims to refine and optimize the system, expanding connection capabilities and fine-tuning key components for broader implementation.

The ultimate objective is to develop AI data centers that not only operate faster but also significantly reduce energy consumption compared to current standards.

Promising Sustainability for AI

Amidst the escalating global energy demands of AI technologies, the NTC’s pioneering work presents a vital solution.

By integrating LEDs, hybrid chip integration, and neuromorphic architecture, the BRIGHT project charts a promising course towards sustainable, low-energy AI solutions.

If successful, this innovative approach could redefine the power sources for artificial intelligence, markedly reducing the environmental impact of future computing technologies.
