- This paper reported the first demonstration of near-field microscopy employing the technique of laser self-mixing, which we previously pioneered in terahertz frequency quantum cascade lasers. This work underpinned a major component of the £6.5M EPSRC Programme Grant (EP/P021859/1). This influential technique has been adopted internationally (e.g., doi:10.1364/OE.26.018423; doi:10.1109/IRMMW-THz.2016.7758743), and has led to record sub-100-nm (doi:10.1021/acsphotonics.7b00687), now sub-30-nm, THz imaging resolutions. This work led to a key-note talk at IQCLSW 2016, new collaborations with the University of Manchester and National Graphene Institute, and leadership of a UK academic/industrial network on terahertz frequency microscopy of 2D/topological materials through the Royce Institute.
