Generation of Optical Frequency Harmonics for Quantum Communication Systems at Side Frequencies
For the first time, a significant effect of passive (i. e., without additional amplification) optical feedback on the number of spectral components of the output signal of a phase microwave integrated optical modulator has been demonstrated. The conditions are revealed under which the number of additional spectral components increases to 2 × 20 pieces, and the spectral range covered by them reaches up to 69 GHz.
It is proposed to use this effect to increase the transmission rate of the quantum key, as well as to expand the functionality of optical communication systems using based on DWDM standards.
