Data transmission in the far infrared range

É. M. Belenov, S. I. Vedeneev


Abstract: An investigation is made of the possibility of using superconducting Josephson weak links (bridges or point contacts) for data transmission and reception in the frequency band ~10¹² Hz in the far infrared region. It is shown that a signal current ~(10^–2–10^–3)I_c is induced in real superconducting point contacts (I_c is the critical superconducting current). Such a signal is considerably greater than the superconducting contact noise or spontaneous noise of the laser medium at the carrier frequency.
