Under ultra - low temperatures that are extremely close to absolute zero (for instance, 4 Kelvin, which is roughly equivalent to -269.15℃), the performance of the majority of electro - optic materials experiences a dramatic decline. In the most recent research endeavor, Belgian scientists have successfully created a groundbreaking strontium titanate (SrTiO3) thin film. This innovative thin film demonstrates not only low optical loss but also record - breaking electro - optic performance when subjected to extremely low temperature environments. It holds great potential for supplying more efficient light - controlled components for quantum modules. The relevant research paper has been featured in the latest edition of the renowned journal "Science".
