Abstract
Gallium-doped germanium (Ge:Ga) extrinsic photoconductor is one of a excellent quantum detector in the terahertz range. Design of a novel wave-guide Ge:Ga photoconductor integrated with silicon solid immersion lens and fabrication technology for linear arrays is presented. The possibilities to extend this technology for realizing large format Ge:Ga waveguide 2D-array detector are discussed.
