| Description | This grant has allowed a detailed investigation of the modulation of two dimensional acoustic waves and THz quantum cascade lasers using bulk acoustic waves. Light modulators for THz radiation are a fundamental component of many potential terahertz systems, and are key to transmission of information by a terahertz carrier wave. The main output from this grant was a Nature Communications paper which demonstrated fast modulation of light output from a THz QCL, a topic on which several further grants are now being written. |
| Exploitation Route | Building new terahertz systems. Fast modulation schemes for THz QCLs leading to new communications systems. |
