“…The resonance wavelength shifts towards longer wavelengths with increasing temperature. This result is in agreement with previous theoretical and experimental analyses made for SOI ring resonators 21,23 . Concurrently, the generated oscillation signal frequency also increases.…”

“…Since the proposed OEO configuration had an oscillation frequency dependent on the refractive index environment of the RR waveguides, we have tested its characteristics for application in measuring optical index variations 21,22 . A simple approach to implement this index change was adopted by changing the sample temperature with the Peltier module, thus changing the temperature of the ring resonator, shifting its resonance wavelength.…”

Si photonics has an immense potential for the development of compact and low-loss opto-electronic oscillators (OEO), with applications in radar and wireless communications. However, current Si OEO have shown a limited performance. Si OEO relying on direct conversion of intensity modulated signals into the microwave domain yield a limited tunability. Wider tunability has been shown by indirect phase-modulation to intensity-modulation conversion, requiring precise control of the phase-modulation. Here, we propose a new approach enabling Si OEOs with wide tunability and direct intensity-modulation to microwave conversion. The microwave signal is created by the beating between an optical source and single sideband modulation signal, selected by an add-drop ring resonator working as an optical bandpass filter. The tunability is achieved by changing the wavelength spacing between the optical source and resonance peak of the resonator. Based on this concept, we experimentally demonstrate microwave signal generation between 6 GHz and 18 GHz, the widest range for a Si-based OEO. Moreover, preliminary results indicate that the proposed Si OEO provides precise refractive index monitoring, with a sensitivity of 94350 GHz/RIU and a potential limit of detection of only 10 8 RIU, opening a new route for the implementation of high-performance Si photonic sensors.

“…The OEO offers a high-speed and high-resolution sensing solution by translating the optical domain resonance wavelength change caused by a strain, temperature, refractive index or transverse load to a frequency change of an RF electrical spectrum [72]. Various OEO based sensing architectures have been reported [76][77][78][79][80][81][82], which includes using phase-shifted fiber Bragg grating (PS-FBG) as strain sensors [76], polarization-maintaining PS-FBG for temperature-insensitive transverse load sensing [77,78], temperature sensors using a single laser source [79], or a Mach-Zehnder interferometer structure built by a broadband optical light source [80], where the frequency drifting problem of the single laser source was eliminated [81]. Looking to the future, the development of a compact and portable OEO sensor in a miniaturized platform has attracted significant interest.…”

Microwave photonics, based on optical filtering techniques, are attractive for wideband signal processing and high-performance sensing applications, since it brings significant benefits to the fields by overcoming inherent limitations in electronic approaches and by providing immunity to electromagnetic interference. Recent developments in optical filtering based microwave photonics techniques are presented in this paper. We present single sideband modulation schemes to eliminate dispersion induced power fading in microwave optical links and to provide high-resolution spectral characterization functions, single passband microwave photonic filters to address the challenges of eliminating the spectral periodicity in microwave photonic signal processors, and review the approaches for high-performance sensing through implementing microwave photonics filters or optoelectronic oscillators to enhance measurement resolution.

“…The challenge is now to transfer the OEO-based topologies onto an integrated platform in order to develop compact and portable solutions for sensing environment variables. The first steps to developing an integrated OEO-based system was first initiated in [77] where we presented an integrated photonic sensor based on an optoelectronic oscillator with an on-chip sensing probe that is capable of realizing high sensitivity and high resolution. This work engaged the use of a SOI microring resonator to continuously select different RF oscillation modes.…”
