Radio-Frequency Multiplication Without Phase Noise Degradation in an Electro-Optic Frequency-Shifting Loop
Résumé
Generating multi-GHz clock signals with low phase noise is a fundamental challenge in many domains including electronic instrumentation, radar ranging, telecommunication, signal intelligence or radio-astronomy. high-frequency from frequency oscillators by conventional analog multiplication hampered the intrinsic degradation of process itself (i.e. 20 log(q), where q multiplicative factor). Conversely, photonics offers efficient sources using combs harmonic mode-locking, but at price complexity and large resources. Recently, technique based on an acousto-optic shifting loop has been reported, allowing RF 80 MHz factors up to 100 [1].
