Ripple Suppression in Broadband Microwave Photonic Phase Shifter Frequency Response

Ripple Suppression in Broadband Microwave Photonic Phase Shifter Frequency Response

This paper presents a detailed investigation on the cause of ripples in the frequency response of a microwave photonic phase shifter implemented using a 90° hybrid coupler. It was found that an unwanted radio frequency (RF) modulation sideband is generated at the modulator output due to the...
