Fiber Optics in Quantum Applications

Fiber optics are crucial to quantum applications including quantum computing and quantum communications. XSOF™ has decades of experience developing custom, innovative fiber assemblies for a wide range of specialized applications, including Quantum. For over twenty years, we’ve worked with Photonic Crystal Fiber, providing PCF assemblies designed to address a wide range of emerging applications in the field of Quantum Information and Science Technology (QIST).

XSOF™ was one of the first companies in the industry to offer high-power PCF cables with beam expanding end caps, and we are experts in this area of fiber optic solutions. Our team has the experience and capabilities to provide our customers with the cutting-edge solutions required by researchers and engineers working in advanced Quantum platforms, such as trapped ion and neutral atom systems. We are one of the few companies today that has extensive experience working with PCF and HCPCF assemblies, and we are fully equipped to provide a wide range of customized solutions.

XSOF’s fiber optic solutions for Quantum Applications

XSOF™ is one of the pioneers of developing PCF cables and assemblies in quantum computing and related applications, and we have many options available for our customers.

Polarization Maintaining-Large Mode Area Photonic Crystal Fibers (PM-LMA PCFs) preserve the polarization state of single mode lasers. They also maintain single-mode transmission of high-power, low noise, narrow line width, single-mode lasers used in quantum systems for trapping/cooling and manipulation of atoms & ions.

We have several end cap options as well. Our HP2.5 termination has enabled engineers and researchers to deliver >20W of single-mode laser power for nearly 10 years. Our custom termination options and ability to integrate PCF into standard fiber optic connector interfaces enables our customers to benefit from the performance advantages of PCF without the need to re-engineer optical tooling and hardware.

Through collaboration with National Laboratories, Universities, small high-tech start-ups, and large multinational corporations, we have developed many proprietary designs and processes that empower our partners and customers to benefit from the unique functionality PCF technology brings to Quantum research applications.
