Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

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. |
