SUMMARY:A Liquid Helium Waveguided Terahertz and Optical Microphotolumines

DESCRIPTION:Combining terahertz and optics at cryogenic temperatures allow
 s to \nexplore a variety of different physical effects\, such as e.g. phot
 on assisted tunneling in self-assembled quantum dots. However\, conducting
  such experiments requires a suitable setup.\n\nIn this talk\, I will show
  a new setup\, that allows to simultaneously \nperform conventional microp
 hotoluminescence spectroscopy and excite the  electrically contacted sampl
 e at liquid helium temperature with terahertz radiation using a waveguided
  delivery system. I will \ndemonstrate the results of performance measurem
 ents and characterisation of the system\, highlight options for focussing 
 terahertz radiation on the sample\, and comment on possible opportunities 
 for experiments with  the system.
