Abstract :
A novel configuration of fiber-optic link is demonstrated which forms a passive microwave noise reduction filter. This circuit is designed to suppress unwanted RF amplitude noise arising from either the transmission laser due to relative intensity noise (RIN), or from an optical amplifier in the form of amplified spontaneous emission (ASE). The optics can be configured to select the center RF frequency of the noise filter as well as the depth and bandwidth for filtering.
