We propose a polarization-insensitive σ-shaped coupled optoelectronic oscillator (σ-COEO) based on an active mode-locking technique and demonstrate that it can generate microwave pulse trains with tunable repetition frequencies. Mode-locking in the time domain is achieved by injecting an external mi...
