Applications Driving Discovery

• Quantum Computing: Achieve sub-MHz linewidths and finesse >100,000 for qubit control and entanglement studies, leveraging ultra-stable cavities with <0.15nm surface roughness to minimize photon scattering—critical for maintaining quantum coherence. These precision components reduce decoherence risks, enabling longer qubit interactions essential for complex quantum algorithms, while their low absorption coatings preserve signal integrity in delicate quantum states, supporting breakthroughs in cryptography and molecular modeling.​
• Ultrafast Spectroscopy: Minimize thermal drift with ultra-low expansion materials, ensuring consistent results over 5+ years, as their <3.0×10⁻⁶/K expansion coefficient resists temperature-induced wavelength shifts. This stability is vital for tracking rapid molecular dynamics, where even nanoscale changes in optical alignment would distort spectral data. Paired with high-reflectivity coatings (420nm–3000nm), they deliver reliable photon flux, enhancing detection sensitivity in studies of chemical reactions and biological processes.​
• Photonics R&D: Modular designs allow rapid reconfiguration—swap mirror mounts or test new coatings in hours, not weeks, accelerating prototyping cycles for next-gen lasers and sensors. With 6 substrate options and customizable coatings, researchers can iterate on cavity designs, optimizing for specific wavelengths or environmental conditions, while Class 100 cleanroom fabrication ensures contamination-free performance, reducing experimental variables in cutting-edge photonics innovations.​
• Case Study: MIT’s Quantum Lab reduced mode-hopping issues by 60% using our actively stabilized cavities, which combined sub-MHz linewidths with thermal resilience (-200°C to 300°C) to maintain stable laser output. This improvement enabled longer qubit coherence times, streamlining data collection in entanglement experiments and accelerating progress toward scalable quantum computing systems, validating the components’ role in high-impact research.
