LIGHT MIXER FOR GENERATING TERAHERTZ RADIATION |
摘要 |
<p>The invention relates to a light mixer for generating terahertz radiation, comprising a photodetector (PHD) coupled to an antenna (AT) for terahertz radiation, characterized in that the photodetector comprises a layer of photoconductive material capable of absorbing optical radiation, said layer having a thickness that is less than the absorption length of said radiation by the photoconductive material and being contained between an at least partially transparent so-called upper electrode and a reflective so-called lower electrode, said lower and upper electrodes comprising a resonant cavity for said optical radiation. The invention further relates to a terahertz radiation source comprising such a light mixer and to two laser radiation sources arranged to stack two laser radiation beams on the upper electrode of the photodetector. The invention also relates to the use of such a light mixer for generating terahertz radiation via light mixing.</p> |
