Introduction
The CW Technology & Engineering Conference (CWTEC) 2026 convenes senior engineers, technologists, academics, and business leaders to examine the technical and strategic challenges facing the UK’s semiconductor and photonics industries. Organised by Cambridge Wireless, this year’s edition carries the theme “Engineering the Next Semiconductor Frontier” and addresses how the UK can strengthen its position in chip design, compound semiconductors, and quantum technologies at a time when global demand for advanced compute and connectivity infrastructure continues to accelerate.
The timing reflects broader industry pressures. Artificial intelligence workloads are driving unprecedented requirements for processing power and energy efficiency. Electrification across transport and industrial sectors is creating new demand for power electronics. Meanwhile, geopolitical tensions have elevated supply chain resilience from an operational concern to a strategic imperative. CWTEC 2026 positions itself as a forum for technically rigorous discussion of these intersecting challenges.
About This Event
CWTEC is an established fixture in the UK technology calendar, drawing over 250 attendees annually. The conference format combines technical presentations with structured debate, emphasising practical perspectives alongside forward-looking analysis. Sessions are designed to be substantive rather than promotional, with content aimed at professionals who work directly with the technologies under discussion.
The 2026 event takes place at 30 Euston Square in London, with online ticket options available for those unable to attend in person. The programme spans the full semiconductor and photonics value chain, from materials science and device physics through to systems integration and commercial deployment.
Semiconductor Design and Future Compute Architectures
A central thread running through CWTEC 2026 concerns the evolution of compute architectures in response to AI, edge computing, and data centre requirements. Traditional silicon scaling continues to face physical and economic constraints, prompting renewed interest in heterogeneous integration, chiplet-based designs, and novel materials that can deliver performance improvements without proportional increases in power consumption.
The UK has historically maintained strength in chip design, particularly in processor architectures and specialised intellectual property. CWTEC examines how these capabilities can be applied to emerging workloads, including inference engines for machine learning, low-latency processing for autonomous systems, and secure computing environments for sensitive applications. The conference also addresses quantum computing architectures, exploring the engineering challenges involved in scaling quantum systems from laboratory demonstrations to practical deployment.
Photonics and Power Electronics
Photonics represents another area where UK research institutions and companies have developed significant expertise. Optical technologies are increasingly critical for high-bandwidth communications, both in long-haul networks and within data centres where electrical interconnects struggle to meet growing throughput demands. Silicon photonics, which integrates optical components onto semiconductor substrates, offers a pathway to mass-produced photonic devices that can be manufactured using existing fabrication infrastructure.
Power electronics receives parallel attention at CWTEC 2026. The transition to electric vehicles, renewable energy systems, and more efficient industrial equipment depends on semiconductors capable of handling high voltages and currents while minimising energy losses. Compound semiconductors such as silicon carbide and gallium nitride have emerged as essential materials for these applications, and the UK has invested in developing domestic capabilities in compound semiconductor manufacturing.
Supply Chain Strategy and Sovereign Capabilities
The semiconductor industry operates through complex global supply chains that have proven vulnerable to disruption. Export controls, trade barriers, and competition for critical materials have transformed supply chain management from a logistics function into a strategic discipline. CWTEC 2026 dedicates significant attention to these dynamics, examining how UK organisations can build resilience while navigating an increasingly fragmented regulatory landscape.
The concept of sovereign capability features prominently in these discussions. While no single country can achieve complete self-sufficiency in semiconductor production, governments are increasingly focused on securing access to critical technologies and reducing dependence on potentially unreliable suppliers. For the UK, this involves identifying where domestic strengths can be leveraged and where strategic partnerships offer the most effective path to supply security.
Critical materials present particular challenges. Many advanced semiconductors require rare earth elements and specialised chemicals with concentrated supply bases. Understanding these dependencies and developing alternative sources or substitute materials has become an active area of both research and policy development.
Energy Efficiency and System-Level Innovation
Energy consumption has emerged as a defining constraint for advanced computing systems. Data centres already account for a substantial and growing share of global electricity demand, and the computational requirements of AI training and inference threaten to accelerate this trend. CWTEC 2026 addresses energy efficiency not as an isolated technical parameter but as a system-level challenge requiring coordinated innovation across devices, architectures, and software.
Improvements at the device level, including more efficient transistor designs and better thermal management, contribute to overall system efficiency. However, architectural choices often have larger impacts, determining how effectively computational resources are utilised and how much energy is consumed moving data between processing and memory elements. The conference explores how these different levels of the technology stack interact and where the greatest opportunities for efficiency gains exist.
Who Should Attend
CWTEC 2026 is structured for professionals who engage directly with semiconductor and photonics technologies or who shape strategy and policy in these sectors. The technical depth of the programme assumes familiarity with the underlying engineering concepts, making it most relevant for those with hands-on experience in design, manufacturing, or systems integration.
Typical attendees include chief technology officers, heads of engineering, R&D directors, and product managers from technology companies working across the semiconductor value chain. Academic researchers and leaders of university programmes in relevant disciplines will find the conference valuable for understanding industry priorities and identifying collaboration opportunities. Policymakers and government strategists responsible for technology and industrial policy can gain insight into the technical realities that should inform strategic decisions.
The event also serves professionals from adjacent sectors where semiconductor and photonics technologies are becoming increasingly important, including telecommunications, automotive, aerospace, and energy. As these industries become more dependent on advanced electronics, understanding the trajectory of underlying technologies becomes essential for informed planning.
The UK’s Position in Global Semiconductor Development
The UK occupies a distinctive position in the global semiconductor landscape. While lacking the high-volume manufacturing capacity concentrated in East Asia, the country maintains recognised strengths in chip design, compound semiconductors, photonics research, and quantum technologies. CWTEC 2026 examines how these capabilities can be developed and connected to address both domestic requirements and export opportunities.
The conference provides a forum for honest assessment of gaps as well as strengths. Identifying where the UK lacks critical capabilities, and determining whether those gaps should be addressed through domestic investment or international partnership, represents an essential input to both corporate and national strategy. CWTEC aims to facilitate these conversations among the technical experts and decision-makers best positioned to act on the conclusions.
