新型钛酸锶薄膜低温电光性能创新高

Core Insights - A new type of strontium titanate (SrTiO3) thin film has been developed by Belgian scientists, demonstrating record electro-optic performance at extremely low temperatures, which could enhance optical control components for quantum modules [1][2] Group 1: Material Performance - The new strontium titanate thin film exhibits low optical loss and exceptional electro-optic performance at temperatures close to absolute zero, specifically at -269.15°C [1] - The material achieved a Pockels coefficient of 350 pm/V at -269.15°C, marking the highest record for any thin-film electro-optic material at this temperature [1] Group 2: Applications and Implications - The high response and low loss characteristics of the material facilitate the development of smaller devices with reduced photon loss, advancing the next generation of quantum interconnects, modulators, and sensors [2] - Another study indicates that by precisely controlling the structure of strontium titanate, its response to electric fields becomes significantly strong and tunable at temperatures between 4-5 Kelvin, highlighting the controllable potential of this material [2]
