               <mods:abstract>Our group purchased a THz photomixer from the Millimeter Wave Technology&#xd;
Group at the Rutherford Appleton Laboratory in London, UK. A photomixer is based on&#xd;
optical heterodyne conversion where a photoconductor or photodiode is illuminated by two&#xd;
laser beams with a difference frequency in the THz region. The beat frequency of the&#xd;
two lasers will modulate the conductivity of the photomixer material. The variation of&#xd;
the conductivity is converted to electrical current and finally radiation by applying a bias&#xd;
voltage across the active region of the device. My thesis concerns the determination of the&#xd;
characteristics of the photomixer, which is an expensive and extremely sensitive piece of&#xd;
equipment, to optimize its performance in support of a number of research activities within&#xd;
the group.</mods:abstract>
