Area of Science:

  • Optics and Photonics
  • Fiber Optic Sensing
  • Interferometry

Background:

  • Wavelength tracking in fiber-optic interferometers is limited by fringe order ambiguity.
  • This ambiguity restricts the dynamic range to half the free spectral range.
  • A new sensing strategy is needed to overcome these limitations.

Purpose of the Study:

  • To propose and demonstrate a new sensing strategy for fiber-optic interferometers.
  • To utilize the dispersion turning point property of optical microfiber couplers.
  • To achieve high sensitivity and overcome fringe order ambiguity in refractive index sensing.

Main Methods:

  • Utilizing the dispersion turning point in an optical microfiber coupler mode interferometer.
  • Approximating the dispersion turning point position using dual peaks/dips.
  • Numerical calculations and experimental demonstration of the sensing strategy.

Main Results:

  • The dispersion turning point position is sensitive to ambient refractive index changes.
  • High sensitivities exceeding 5327.3 nm/RIU were achieved across a refractive index range of 1.333-1.4186.
  • The sensor demonstrated high resolution and linearity, with potential for further improvement by increasing coupler length.

Conclusions:

  • The proposed sensing strategy effectively utilizes the dispersion turning point for refractive index sensing.
  • This method overcomes the limitations of traditional wavelength tracking, offering a wider dynamic range.
  • The optical microfiber coupler mode interferometer shows significant potential for high-performance sensing applications.
