Triangular Waveforms Generation Based on an Dual-Loop Optoelectronic Oscillator

A novel scheme for the generation of full-duty-cycle triangular pulses based on an optoelectronic oscillator (OEO) was proposed and experimentally demonstrated. With the employment of the Chirped Fiber Bragg Grating, the "Vernier effect" was realized, which can effectively improve the side mode suppression ratio. The triangular pulses train with repetition of 6 GHz respectively was obtained successfully in experiment.
