Researchers have demonstrated that a specific class of oxide membranes can confine infrared light much more effectively than bulk crystals, which has promising implications for next-generation infrared imaging technologies. These thin-film membranes maintain the desired infrared frequency while compressing wavelengths, allowing for greater image resolution.
Researchers have successfully shown that a particular type of oxide membranes can effectively confine, or “squeeze,” infrared light. This breakthrough could enhance future infrared imaging technologies. These thin-film membranes outperform traditional bulk crystals in confining infrared light. For this work, the researchers worked with transition metal perovskite materials. Specifically, the researchers used pulsed laser deposition to grow a 100-nanometer-thick crystalline membrane of strontium titanate in a vacuum chamber. The crystalline structure of this thin film is high quality, meaning that it has very few defects. These thin films were then removed from the substrate they were grown on and placed on the silicon oxide surface of a silicon substrate.
“This work establishes a new class of optical materials for controlling light in infrared wavelengths, which has potential applications in photonics, sensors, and thermal management,” Liu says. “Imagine being able to design computer chips that could use these materials to shed heat by converting it into infrared light.”
