Theoretical model of tunable optoelectronic oscillator

Abstract

A theoretical model of an electronically tunable multi-loop optoelectronic oscillator (OEO) based on photonic and microwave spin-wave delay lines has been developed. The theory takes into account a dispersion of electromagnetic waves in optical fibers and a dispersion of spin waves in ferrite films. An expression for transfer function of the OEO circuitry was derived. The theory enables one to calculate transmission characteristics and suppression of spurious harmonics of the multi-loop OEOs.
