Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Area of Science:

  • Optics and Photonics
  • Fluid Dynamics
  • Materials Science

Background:

  • Liquid-core/liquid-cladding (L2) optical fibers offer unique light-guiding properties.
  • Precise control over the liquid core's geometry and position is crucial for L2 fiber functionality.
  • Existing methods often struggle with maintaining a stable, centered core, especially with varying flow conditions.

Purpose of the Study:

  • To present an integrated tunable L2 optical fiber.
  • To demonstrate a novel hydrodynamic focusing scheme for precise liquid core formation.
  • To achieve a tunable and centered circular liquid core irrespective of flow-rate ratios.

Main Methods:

  • Development of a novel three-dimensional hydrodynamic focusing system.
  • Integration of the focusing scheme into an L2 optical fiber platform.
  • Experimental validation of core stability and tunability under varying flow conditions.

Main Results:

  • Successful production of a tunable circular liquid core.
  • Demonstration of core centering regardless of cladding and core liquid flow-rate ratios.
  • Confirmation of the stability and robustness of the L2 fiber design.

Conclusions:

  • The novel 3D hydrodynamic focusing scheme enables robust and tunable L2 optical fiber fabrication.
  • This technology overcomes previous limitations in core stability and flow-rate dependency.
  • The developed L2 fiber holds potential for various applications in photonics and sensing.
