Area of Science:

  • Optoelectronics
  • Fiber Optic Sensors
  • Interferometry

Background:

  • Mach-Zehnder interferometers (MZIs) are widely used in sensing applications.
  • Traditional MZI fabrication can be complex and costly.
  • Developing compact and highly sensitive fiber optic sensors remains a key research area.

Purpose of the Study:

  • To introduce a novel miniature two-path Mach-Zehnder interferometer (MTP-MZI) fiber sensor.
  • To demonstrate high sensitivity for curvature measurement.
  • To investigate the sensor's performance in temperature sensing and address cross-sensitivity.

Main Methods:

  • Fabrication of the MTP-MZI sensor by coupling and fusing multimode fiber (MMF) with single-mode fiber (SMF) using arc fusion technology (AFT).
  • Experimental evaluation of the sensor's response to varying curvature.
  • Experimental evaluation of the sensor's response to varying temperature.

Main Results:

  • The MTP-MZI sensor achieved a maximum curvature sensitivity of -96.70 dB/m-1 in the range of 0.0418 m-1 to 0.0888 m-1.
  • The sensor exhibited a maximum temperature sensitivity of 212 pm/°C in the range of 30 °C to 70 °C.
  • The developed sensor demonstrated low temperature cross-sensitivity.

Conclusions:

  • The miniature MTP-MZI fiber sensor offers an innovative and cost-effective solution for high-sensitivity curvature sensing.
  • The sensor's low temperature sensitivity effectively mitigates cross-sensitivity issues.
  • The MTP-MZI provides a new platform for developing multidimensional and multiparameter fiber optic sensing systems.
