Abstract

This paper describes a mathematical model of a balanced opto-electronic phase-locked loop (OPLL), which is required to be very fast for some network applications. OPLL is investigated in terms of clock pulse width, loop filter gain and residuals of the balancing DC level. Based on the guidelines from the theoretical evaluations, a very simple experimental demonstration including a single electroabsorption modulator as phase comparator is constructed.
