Abstract :
A tunable photonic microwave filter using a simple and tunable multiwavelength semiconductor fibre laser incorporating a high-birefringence Sagnac loop is demonstrated. The wavelength spacing of the laser can be easily varied using optical switches, which in turn allows the free-spectral-range of the photonic microwave filter to be digitally tuned.
