Special Issue Information

Dear Colleagues,

The field of photonic sensors has undergone tremendous growth and advancement in recent years. Photonic sensors offer a number of metrics, such as small size, high sensitivity, low cost and immunity to electromagnetic interference, and geometric versatility, which can handle arbitrary shapes. The ability of photonic sensors has been enhanced to substitute traditional sensors for acoustics, vibration, electric and magnetic field measurement, acceleration, rotation, temperature, pressure, linear and angular position, strain, humidity, viscosity, chemical measurements, and a host of other sensor applications. They can be used in high-voltage, high-temperature, or corrosive environments due to their dielectric property. In addition, these sensors are compatible with communication systems and have the capacity to carry out remote sensing.

In this Special Issue on “Photonic Sensors”, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Micro- and nano-structured fiber sensors;
  • Distributed and multiplexed sensing and sensor networking;
  • Interferometric, polarimetric, and laser-based sensors;
  • Physical, mechanical, and electromagnetic sensors;
  • Chemical, environmental, biological, and medical sensors and biophotonics;
  • New elements (fibers, devices, and subsystems), effects (e.g., plasmonics), technologies (including nanophotonics) and materials (e.g., meta- and structured-materials, etc.) for photonic sensing;
  • Integrated photonics, cavity opto-mechanics and quantum sensing techniques, precision metrology, and frequency combs.

A novel configuration for a polarimetric fiber ring laser incorporating a coupled optoelectronic oscillator (COEO) is proposed and experimentally demonstrated, and its application to magnetic field sensing is studied. The COEO-based polarimetric fiber ring laser has two mutually coupled loops: the fiber ring laser loop and the OEO loop. In the fiber ring laser loop, longitudinal modes break up into orthogonal polarization modes because of birefringence. The frequency of the polarization mode beat (PMB) signals is determined by the cavity birefringence. In the OEO loop, a microwave signal with its frequency equal to the PMB signal is generated. By feeding the oscillation mode to modulate the optical loop, mode-locking can be achieved, rendering the mode spacing of the laser equal to the frequency of the oscillating OEO mode. We can estimate the birefringence variation by measuring the oscillating frequency of the COEO. To validate the proposed sensing system, a circular birefringence change is introduced in a magneto-optic crystal via the Faraday rotation effect. Then, the magnetic field sensing is implemented. Such configuration can achieve single longitudinal oscillation and realize high-speed and high-precision measurements. Full article
