Calculations for the measure of the achievable phase noise reduction by the utilization of optimized multiloop opto-electronic oscillators

This paper is concerned with the analization of the real operation of optimized multiloop opto-electronic oscillator. Preceding works of the authors have proven the validity of a beneficial modification of the conventional opto-electronic oscillator (OEO) configuration. By the optimization of its multiloop structure one may easily achieve significant phase noise suppression in the output signal of the oscillator. Recent study aims for getting explicit expressions for describing this enhancement in the operation. Mathematical results are also supported by measurement results, also introduced.
