Special Issue Information

Dear Colleagues,

An optical resonator has the advantages of high energy density, high quality factor and small spatial size. It has a good application prospect in quantum communication, nonlinear optics, narrowband filtering, and especially, the sensor. The theoretical and experimental research based on the optical resonator sensor has very important scientific significance for the development of the sensor.

This Special Issue is addressed to all types of sensors based on optical resonator and designed for temperature sensing, strain detection, pressure measurement, gas sensing, magnetic field detection and biosensing, etc.

Antiresonant hollow core fibers (ARHCFs) have gained some attention due to their notoriously attractive characteristics on managing optical properties. In this work, an inline optical fiber sensor based on a hollow square core fiber (HSCF) is proposed. The sensor presents double antiresonance (AR), namely an internal AR and an external AR. The sensor was designed in a transmission configuration, where the sensing head was spliced between two single mode fibers (SMFs). A simulation was carried out to predict the behaviors of both resonances, and revealed a good agreement with the experimental observations and the theoretical model. The HSCF sensor presented curvature sensitivities of −0.22 nm/m−1 and −0.90 nm/m−1, in a curvature range of 0 m−1 to 1.87 m−1, and temperature sensitivities of 21.7 pm/°C and 16.6 pm/°C, in a temperature range of 50 °C to 500 °C, regarding the external resonance and internal resonance, respectively. The proposed sensor is promising for the implementation of several applications where simultaneous measurement of curvature and temperature are required. Full article
