Highly efficient THz sources for low-temperature applications

Photo-conductive switches (PCS) have been used for the generation and detection of THz sources for decades now. In recent years, PC switches have been used for applications where high efficiency is required, such as in low-temperature cryogenic environments and high magnetic fields. We investigate n...

description Photo-conductive switches (PCS) have been used for the generation and detection of THz sources for decades now. In recent years, PC switches have been used for applications where high efficiency is required, such as in low-temperature cryogenic environments and high magnetic fields. We investigate novel photoconductive switch designs and their nanofabrication. The new photoconductive switch design is made of several hundreds of nano-pillars and has a three-dimensional, vertical design, which allows for optimisation of optical absorption. The new design achieves optical absorption efficiency exceeding 98 % and is numerically predicted to have efficiencies as high as 50 times better than conventional designs. In this study, we will present the operation principle of the novel PCS as well as preliminary nanofabrication and measurement data.
