“…Higher interrogation speed can also be achieved with the help of a digital signal processor (DSP). As a result, MPS has attracted increasing interest and a variety of high-performance MPS devices have been proposed [ 7 – 12 ]. The center frequency of microwave photonic filters (MPFs) can usually be widely tuned, which can be used to monitor the changes that the system senses.…”

Microwave photonic sensors are promising for improving sensing resolution and speed of optical sensors. In this paper, a high-sensitivity, high-resolution temperature sensor based on microwave photonic filter (MPF) is proposed and demonstrated. A micro-ring resonator (MRR) based on silicon-on-insulator is used as the sensing probe to convert the wavelength shift caused by temperature change to microwave frequency variation via the MPF system. By analyzing the frequency shift with high-speed and high-resolution monitors, the temperature change can be detected. The MRR is designed with multi-mode ridge waveguides to reduce propagation loss and achieves an ultra-high Q factor of 1.01 × 106. The proposed MPF has a single passband with a narrow bandwidth of 192 MHz. With clear peak-frequency shift, the sensitivity of the MPF-based temperature sensor is measured to be 10.22 GHz/°C. Due to higher sensitivity and ultra-narrow bandwidth of the MPF, the sensing resolution of the proposed temperature sensor is as high as 0.019 °C. Graphical Abstract

“…Indeed, with OEOs it is possible to carry out the measurement or sensing of length, refractive index, temperature, angular velocity, load, strain, lowpower RF signal, magnetic field, amongst others (see Refs. [8][9][10][11][12][13][14][15][16] and references therein). For this purpose, several architectures were proposed for the efficiency of the method.…”

“…The fundamental principle of using OEO for optical metrology is to code the quantity to evaluate, such as temperature, strain, transverse load, refractive index, and more, to the frequency shift of oscillating signal of OEOs. Two mechanisms are possible [16]: The first one consists of using the band-pass of the microwave photonic filter both as an oscillation frequency selection element as well as a sensing/measurement element. Even if it gives high sensitivity for optical metrology, it is not easy to implement experimentally.…”

In this work, we use the cubic-nonlinear optoelectronic oscillator (CNOEO) in three different configurations to successfully perform the sensings of temperature, refractive index, and distance measurement with high precision. From our results, the use of the CNOEO through the variation of the values of the cubic-nonlinear parameter increases the sensitivity of the different sensings and the measurement carried out compared to the results obtained with the standard OEO which is a particular CNOEO featuring a cubic-nonlinear parameter equal to zero.
