In collaboration with the Integrated Quantum Optics group we published a paper in the Journal of Applied Physics with the title “Photorefraction management in lithium niobate waveguides: High-temperature vs cryogenic solutions”.
Our research investigates how the photorefractive effect limits power and spectral stability in lithium niobate waveguides at both high and cryogenic temperatures. To address these limitations in environments where heating is impractical, we propose using an auxiliary light source to counteract photorefractive and pyroelectric effects, offering a power-efficient solution for quantum and space applications.
