OPTO-ELECTRONIC TECHNIQUES FOR REDUCING PHASE NOISE IN A CARRIER SIGNAL BY CARRIER SUPPRESSION
摘要
An oscillator (101) for producing a carrier signal and having an opto-electronic noise suppression module (102) connected between an oscillator output coupler (104) and a control input (164) of the oscillator (101). The opto-electronic noise suppression module (102) includes an opto-electronic unit (110) for producing a first electrical signal (121) indicative of a delayed version of the carrier signal. An electrical interferometer (120) receives the first electrical signal (121) and a second electrical signal indicative of the carrier signal to produce two signals which are combined in a mixer (144) to produce a control signal (152) for the oscillator.
