Optical amplification for quantum sources of ultra-stable optical Optical amplification for quantum sources of ultra-stable optical frequency

Popis výsledku v původním jazyce

The reach of any all-optical transmission is limited by attenuation of transmission path and other factors as signal to noise ratio, and it can be extended by all-optical amplification. Bidirectional single fibre transmission introduces an issue of bidirectional symmetrical amplifiers in order not to lose advantage of path symmetry. In case of time transfer, quasi-bidirectional amplification might be acceptable when supported by specific arrangements, e.g. as much as possible equal arrangement for disjoint segments of the path. Time transfer with best available accuracy or optical frequency transfers require single path optical amplifiers that are further considered. In this constitution, unfortunately, reflections together with Rayleigh back-scattering will create feedback. In case feedback is strong enough and discrete amplifier operates in high gain regime (about 20dB), the whole system will start to oscillate. It saturates the gain of amplifiers and also can generate errors, when lasing in a transmission band. In the article, we review possible all optical amplification methods including those allowing to use untraditional transmission bands (outside C band).
