Optimum optical designs for diffraction-limited terahertz spectroscopy and imaging systems using off-axis parabolic mirrors
Nishtha Chopra, James Lloyd-Hughes
Off-axis parabolic mirrors (OAPMs) are widely used in the THz and mm-wave communities for spectroscopy and imaging applications, as a result of their broadband, low-loss operation…
Hot electron cooling in InSb probed by ultrafast time-resolved terahertz cyclotron resonance
Chelsea Q. Xia, Maurizio Monti, Jessica L. Boland +4
Measuring terahertz (THz) conductivity on an ultrafast time scale is an excellent way to observe charge-carrier dynamics in semiconductors as a function of time after photoexcitati…
Precise and accurate control of the ellipticity of THz radiation using a photoconductive pixel array
C. D. W. Mosley, J. Deveikis, J. Lloyd-Hughes
Full control of the ellipticity of broadband pulses of THz radiation, from linear to left- or right-handed circular polarization, was demonstrated via a 4-pixel photoconductive emi…
Intertube excitonic coupling in nanotube van der Waals heterostructures
M. G. Burdanova, M. Liu, M. Staniforth +7
Excitons dominate the optics of atomically-thin transition metal dichalcogenides and 2D van der Waals heterostructures. Interlayer 2D excitons, with an electron and a hole residing…
Tracking a hysteretic and disorder-broadened phase transition via the electromagnon response in improper ferroelectrics
C. D. W. Mosley, D. Prabhakaran, J. Lloyd-Hughes
We demonstrate that electromagnons can be used to directly probe the nature of a phase transition between magnetically ordered phases in an improper ferroelectric. The antiferromag…
Landau polaritons in highly non-parabolic 2D gases in the ultra-strong coupling regime
Janine Keller, Giacomo Scalari, Felice Appugliese +11
We probe ultra-strong light matter coupling between metallic terahertz metasurfaces and Landau-level transitions in high mobility 2D electron and hole gases. We utilize heavy-hole…
