Rice University researchers have identified a way to utilize the \u201cnew terahertz gap\u201d using strontium titanate, enabling the development of innovative optical technologies in the 3-19 terahertz range. This discovery could lead to advancements in quantum materials and medical diagnostics.<\/p>\n
Metal oxide\u2019s properties could enable a wide range of terahertz frequency photonics.<\/p>\n
Visible light is a mere fraction of the electromagnetic spectrum, and the manipulation of light waves at frequencies beyond human vision has enabled such technologies as cell phones and CT scans.<\/p>\n
The Importance and Challenges of the Terahertz Gap
\n\u201cOptical technologies in this frequency region \u23af sometimes called \u2018the new terahertz gap\u2019 because it is far less accessible than the rest of the 0.3-30 terahertz \u2018gap\u2019 \u23af could be very useful for studying and developing quantum materials for quantum electronics closer to room temperature, as well as sensing functional groups in biomolecules for medical diagnosis,\u201d Zhu said.<\/p>\n
