Abstract: Abstract We propose an injection-locked optoelectronic oscillator (OEO) based wide-band frequency doubler, which is free from phase noise deterioration in electrical doubler, by using a dual-parallel Mach–Zehnder modulator (DPMZM). Through adjusting the optical phase shifts… read more here.
