Query: Injection Locking of Optoelectronic Oscillators with Large Delay   The optoelectronic oscillator is a delay line oscillator that leverages
optical fiber technology to realize the large delay required for low phase
noise systems. Spurious sidemodes are an artifact of the delay line oscillator,
yet treatments of injection locking of optoelectronic oscillators have relied
on the application of classical injection locking theory valid only for single
mode oscillators. The large delay contributed by the optical fiber delay line
is accounted for by classical theory only in part through the quality factor Q
that captures the round-trip group delay in a neighborhood of the oscillation
frequency. This paper presents a new formulation of time delay oscillators
subject to injection that describes all the essential features of their
dynamics and phase noise. The common assumptions of a single mode oscillator
and weak injection are removed. This is important to correctly predict the
locking range, the suppression of sidemodes and the phase noise spectrum. The
findings of the analysis are validated by experimental measurements provided by
an optoelectronic oscillator under injection by an external source.
