Special Issue Information

Dear Colleagues,

Quantum-enhanced sensors enable us to acquire unprecedent sensitivity and precision for many measurements and explorations in various scenarios, including but not limited to electric and magnetic fields, acceleration, gravity and exotic forces. Most of these applications benefit from the utilization of light–matter interactions platforms such as atomic magnetometers/comagnetometers, atomic clocks and optomechanical systems. At present, the question of how we can develop more versatile quantum sensors and further improve their performance for sensing applications is attracting great interest from researchers. This Special Issue is expected to advance and develop novel quantum-enhanced sensing technology and related techniques. Topics include, but are not limited to, the following:

  • Novel design and simulation of quantum sensors;
  • Progress on improvement on quantum enhanced sensors and systems;
  • Novel principles and technology on light-matter interactions;
  • Optical detection techniques;
  • Signal detection and control of photonics devices;
  • Advanced manufacturing and integration technologies;
  • Noise analysis and suppression methods;
  • Applications using quantum enhanced sensors;
  • Other quantum metrology with optical systems.

This article examines the impacts of mode hopping on the sensing performance of optical frequency domain reflectometry (OFDR) and explores the potential for developing economical OFDR interrogators employing low-cost distributed feedback (DFB) lasers. By conducting numerical simulations, this study reveals that mode hopping has minimal effects on distance sensing measurements in free space due to the limited duration of beat interference signal at the incorrect frequency within the coherence length. Additionally, the simulations indicate that mode hopping only slightly affects the distributed strain sensing of OFDR, resulting in an error range of less than ±1µε when 100µε is applied to the sensing fiber. These findings highlight the potential of using low-cost DFB lasers with a 1-nm wavelength sweep range and a 1-MHz linewidth as tunable laser sources in OFDR while maintaining reliable and accurate sensing performance.
