An arbitrary spectral synthesis scheme with parallel-connecting high-birefringence fiber loop mirrors (HiBi-FLMs) based on Fourier synthesis theory has been proposed and demonstrated. Three typical spectra of triangle, rectangle, and sawtooth shape have been synthesized by implementing only four HiBi-FLMs. The experimental results are in good agreement with theoretical simulations with goodness of fit of 0.9565. Furthermore, higher precise optical spectrum with narrower bandwidth can he obtained by adopting longer polarization-maintaining fiber and more sections of HiBi-FLMs. Besides, a typical application of arbitrary waveform generation has been implemented. By incorporating with frequency-to-time mapping, triangle- and sawtooth-shaped electrical pulses with repetition rate of 1 GHz and pulse width of similar to 860 ps have been generated.
