摘要： A modified Sagnac loop phase-modulated microwave photonic link with a pulsed optical source is disclosed. Unlike a conventional Sagnac loop, the optical phase offset of the loop can be adjusted to quadrature by applying a synchronized modulation signal to an in-loop phase shifting phase modulator. Thereby, it exemplifies the fundamental RF response.
