Special Issue Information

Dear Colleagues,

Since the microwave generation by an optical link followed by a feedback loop, called an optoelectronic oscillator (OEO) was proposed, several analyses and configurations were proposed. The OEO aspects, such as tunability, side mode components, frequency stability, and phase noise, are currently under active investigation. Single- and multi-feedback loops were proposed, and RF signal injection studies were carried out. Oscillators are critical subsystems in microwave technology and can be used for different purposes, such as frequency reference signals, receivers, and filters. An additional use of the OEOs is as sensors. With varying construction approaches, the OEOs can be implemented with discrete components and as integrated optics components.

This Special Issue invites manuscripts that introduce the recent advances in optoelectronic oscillators and also review papers. All theoretical, numerical, and experimental papers are accepted. Topics include, but are not limited to, the following:

  • Optoelectronic oscillators;
  • Applications of optoelectronic oscillator;
  • Injection and pulling effects for optoelectronic oscillators;
  • Output signal characteristics of optoelectronic oscillators;
  • Simulation of optoelectronic circuit;
  • Optoelectronic oscillator technology;
  • Integrated optics and optoelectronic oscillators;
  • Microwave output signal shaping;
  • Pulsed microwave generation.

Optoelectronic oscillators (OEOs) have emerged as indispensable tools for generating low-phase-noise microwave and millimeter-wave signals, which are critical for a variety of high-performance applications. These include radar systems, satellite links, electronic warfare, and advanced instrumentation. The ability of OEOs to produce signals with exceptionally low phase noise makes them ideal for scenarios demanding high signal purity and stability. In radar systems, low-phase-noise signals enhance target detection accuracy and resolution, while, in communication networks, such signals enable higher data throughput and improved signal integrity over extended distances. Furthermore, OEOs play a pivotal role in precision instrumentation, where even minor noise can compromise the performance of sensitive equipment. This review examines the progress in OEO technology, transitioning from classical designs relying on long optical fiber delay lines to modern integrated systems that leverage photonic integration for compact, efficient, and tunable solutions. Key advancements, including classical setups, hybrid designs, and integrated configurations, are discussed, with a focus on their performance improvements in phase noise, side-mode suppression ratio (SMSR), and frequency tunability. A 20-GHz oscillation with an SMSR as high as 70 dB has been achieved using a classical dual-loop configuration. A 9.867-GHz frequency with a phase noise of −142.5 dBc/Hz @ 10 kHz offset has also been generated in a parity–time-symmetric OEO. Additionally, integrated OEOs based on silicon photonic microring resonators have achieved an ultra-wideband tunable frequency from 3 GHz to 42.5 GHz, with phase noise as low as −93 dBc/Hz at a 10 kHz offset. The challenges in achieving fully integrated OEOs, particularly concerning the stability and phase noise at higher frequencies, are also explored. This paper provides a comprehensive overview of the state of the art in OEO technology, highlighting future directions and potential applications. Full article
