Abstract :
Experimental demonstration of heterodyne optical phase-locked loop (oPLL), using simplest optics, is carried out. For the first time, the effect of loop delay has been experimentally characterized and compared directly to the most significant oPLL configurations. It demonstrates a linewidth tolerance of 6.5 MHz if FEC codes are used.
