Optical-to-RF phase shift conversion-based microwave photonic phase shifter using a fiber Bragg grating.

A novel microwave photonic phase shifter structure is presented. It is based on the conversion of the optical carrier phase shift into an RF signal phase shift via controlling the carrier wavelength of a single-sideband RF-modulated optical signal into a fiber Bragg grating. The new microwave photonic phase shifter has a simple structure and only requires a single control to shift the RF signal phase. It also has the ability to realize multiple phase shifts. Experimental results demonstrate a continuous 0°-360° phase shift with low amplitude variation of <2 dB and low phase deviation of <5° over a wideband microwave range.
