• 論文の詳細を見る

• We presented a recently developed compact solid-state far-infrared and sub-mm(terahertz) source. The radiation is generated by the optical heterodyne conversion (photomixing)in a low-temperature-grown GaAs (LTG-GaAs) photoconductor with a sub-picosecond responsetime. In photomixing, two frequency-offset laser beams are used to illuminate the photoconductor,resulting in the photocurrent oscillation at the difference frequency that drives a planar antenna onthe device. Such a photonic source has the great advantage of compactness, wide tuning range andhigh efficiency over existing electronic devices, and would be suitable for use as local oscillators inheterodyne receivers for IR/sub-mm astronomy.
