D07–The absorption enhancement effect of metal gratings integrated Silicon-based Blocked-Impurity-Band (BIB) terahertz detector
High-sensitivity Terahertz (THz) detection technology is widely researched for its potential applications in astronomical observation, human security check, weak signal biomacromolecule detection, etc. In this work, a novel THz detector based on metal gratings/Si-BIB hybrid structure is theoretically simulated and successfully fabricated. From FDTD simulation results, the optical field is localized in the absorbing-layer region […]
