Eindhoven, the Netherlands, December 10, 2025 -- MicroAlign, a fibre array manufacturing company specialising in alignment of optical fibres, has achieved a major milestone in high-accuracy fibre array technology.

The company successfully scaled its fibre array port count from 12 to 24 channels while maintaining  100-nanometer fibre-core pitch accuracy, enabling ultra-low-loss fibre-to-photonic chip coupling for quantum computing applications. This achievement surpasses the current state-of-the-art.

Achieving ultra-low coupling loss between photonic chips and optical fibre arrays is a fundamental requirement for advancing the performance and scalability of quantum photonic computing systems.

The fibre-core position within fibre arrays is a critical factor in reducing the fibre-to-chip loss per port. Traditional V-groove-based fibre arrays typically provide a core position accuracy of approximately 0.5 µm, which is insufficient to meet the requirements of next-generation quantum photonic computers.

”It is crucial that we keep a fast innovation pace to timely intercept the industry requirements of photonic quantum computing, and of photonic high-end applications where every bit of optical energy is precious,” said Simone Cardarelli, CEO of MicroAlign

MicroAlign introduces a novel concept of ultra-high-accuracy fibre arrays, in which each fibre core is actively aligned during the manufacturing process. Unlike passive alignment methods, this technique enables simultaneous, closed-loop alignment of all fibres, resulting in a new benchmark for efficient optical fibre connectivity.

“This milestone further demonstrates how the unique features of MicroAlign fibre manipulation  technology can enable the manufacturing of fibre arrays with a large number of channels without  compromising the core position accuracy”, says Marco Fattori, CTO of MicroAlign

The company will present the results of its 24-channel fibre arrays at the upcoming SPIE Photonics  West Conference, the world’s leading event for lasers, biomedical optics, optoelectronics, and emerging technologies spanning biophotonics, quantum, and vision systems.
