Tunable and integrated RF photonic phase shifter based on phase modulation and FBG filtering

An integrated RF photonic phase shifter that can achieve a tunable phase shift with little RF amplitude variation is presented. The beating between phase-modulated optical carrier and the first-order sideband can generate RF signal with desired phase shift. Results show the RF phase shifter can achieve a continuous 0° − 360° phase shift with low amplitude variation.
