Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass through many materials without causing damage, making them useful for security scanning, medical imaging, and high-speed wireless communication. Unlike visible light or radio waves,...

Distributed acoustic sensing (DAS) systems represent cutting-edge technology in infrastructure monitoring, capable of detecting minute vibrations along fiber optic cables spanning tens of kilometers. These systems have proven invaluable for applications ranging from earthquake detection and oil exploration to railway monitoring and submarine cable surveillance. However, the massive amounts of data generated by these systems create a significant bottleneck in...

Quantum computing has the potential to revolutionize information processing by leveraging the principles of superposition, entanglement, and quantum interference. Photonic quantum computing, in particular, is emerging as a promising platform due to its intrinsic scalability, robustness to decoherence, and ability to operate at room temperature. Recent advances in integrated photonic circuits, quantum light sources, quantum memory, and quantum error correction are rapidly shaping the future of th

Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. However, the existing bench-top spectroscopy systems are too large, complex, and impractical for narrow-space use. Furthermore, the traditional laser spectroscopy techniques use bulky components like light sources, mirrors, detectors, and gas cells to det
