Driving Quantum Forward: A Look Back at June’s Industry Events

Photonics is a critical enabler of emerging quantum technologies, providing the foundational building blocks for quantum sensing, communications, navigation, and computing platforms. Through its portfolio of advanced photonic components and integrated technologies, including laser sources, optical amplifiers, and photonic integrated circuits, indie helps support the development of next-generation quantum systems. As quantum-enhanced sensing and navigation move closer to commercialization, advances in photonics will play an increasingly important role in delivering the precision, reliability, and performance required across automotive, aerospace, industrial, and defense applications.

Bridging Research and Industrialization

From Quantum Experiments to Scalable Quantum Systems

At the Optica Quantum Industry Summit in Glasgow, Philipp Vorreau, VP & General Manager of SLEDs in indie’s Photonics Division, presented how next-generation laser technology can help overcome one of the most important challenges facing the quantum industry today: scalability.

For years, remarkable advances in quantum computing, quantum sensing, and quantum communications have demonstrated the immense potential of quantum technologies. Yet many of these systems still depend on complex laser architectures built around external-cavity lasers, alignment-sensitive optics, and bulky frequency conversion schemes. As systems scale from a handful of quantum channels to hundreds or thousands, these laser infrastructures become increasingly difficult to manage, replicate, and manufacture. The reality is simple: many quantum systems are no longer limited by the quantum physics itself—they are limited by the complexity of the photonic hardware required to control them.

A New Generation of Visible DFB Lasers

At the Summit, Philipp Vorreau showcased indie’s novel visible and near-infrared DFB laser platform, specifically developed to address this challenge. While DFB lasers have long been the backbone of the telecommunications industry, extending this technology into visible quantum wavelengths represents a significant breakthrough. indie’s technology enables native single-frequency lasers at many of the wavelengths required by trapped-ion, neutral-atom, atomic clock, and quantum sensing systems.

The platform is designed to be wavelength-agnostic across a broad spectrum from UV to deep green and has already demonstrated operation at several key quantum wavelengths used for ytterbium-based quantum systems and others.

Building the Photonic Foundation for Quantum

Visible DFB lasers are only part of the story. The presentation also highlighted indie’s broader portfolio of enabling photonic technologies, including ultra-low-noise NIR laser modules, tunable optical filters, and photonic integrated circuit approaches that together support quantum computing, communications, and sensing architectures. Yet the key message remained clear: As quantum technologies move from laboratory demonstrations to commercially deployed systems, the photonic infrastructure must become simpler, more reliable, and inherently scalable.

Novel visible DFB lasers represent an important step toward that future. By replacing complex laser architectures with compact, manufacturable semiconductor solutions, they help transform quantum systems from research instruments into scalable products.

In parallel, we exhibited at Optica Quantum 2.0 Conference, where we showcased our live Visible Distributed Feedback Laser Diodes demo.

Built on advanced GaN semiconductor technology, these single-frequency laser diodes operate across wavelengths from 375 nm to 535 nm, providing the spectral purity, wavelength stability, and precision required for targeting specific atomic transitions and controlling quantum states. These capabilities make them particularly relevant for:

• Quantum Computing
• Quantum Communications
• Atomic Clocks
• Quantum Sensors
• Optical Pumping and Atomic Control Systems

Live in Boston

At Quantum.Tech World in Boston, we extended our live demonstration to include our ultra-stable, narrow-linewidth near-infrared laser module, the LXM.

The LXM Narrow-Linewidth Laser Module is an industrialized, compact laser source designed for applications that require exceptional frequency stability and ultra-low phase noise. Built on indie’s proprietary laser diode technology, the new LXM-Elite delivers single-frequency performance with linewidths reaching 20 Hz, making it particularly well suited for demanding quantum applications and coherent optical systems.

During the event, visitors were able to observe a live demonstration of the module’s multi-wavelength stability in an uncontrolled environment, highlighting the robustness and reliability required for deployment beyond the laboratory.

The LXM platform addresses several critical requirements for emerging quantum architectures, including:

• Quantum Key Distribution (QKD)
• Atomic Frequency stabilization
• Precision metrology
• Coherent Optical Communications
• Quantum Sensing and Distributed Fiber Sensing Systems

Complementing the laser source, indie is also developing a broader portfolio of quantum-enabling photonic technologies, including:

• High-performance optical filters for signal isolation and spectral shaping
• Dispersion compensation solutions that facilitate integration into existing optical network infrastructures
• Advanced photonic integration and packaging platforms designed to support scalable quantum systems

Continuing to Build

For indie, the conversations held throughout June reinforced a clear direction: developing the enabling photonic technologies that will help transform quantum concepts into practical and deployable solutions.

The enthusiasm and engagement we experienced at both Optica Quantum 2.0 and Quantum.Tech World highlighted the growing momentum behind quantum technologies. Through live demonstrations, technical presentations, and meaningful industry discussions, we saw firsthand the increasing demand for high-performance, manufacturable photonic solutions that are needed in the quantum industry.
