Sound Waves: Resonance01:14

Sound Waves: Resonance

Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...

Area of Science:

  • Photonics
  • Optical sensing
  • Materials science

Background:

  • Whispering gallery modes (WGM) are sensitive to microsphere morphology.
  • Dielectric microspheres can be utilized as optical resonators.

Purpose of the Study:

Main Methods:

  • Excitation of WGM using evanescent coupling from a tunable diode laser and tapered fiber.
  • Application of compressive force to microsphere resonators (silica, solid/hollow PMMA).
  • Tracking of WGM shifts induced by force-induced changes in sphere shape and refractive index.

Main Results:

  • Demonstrated a micro-optical force sensor based on WGM shifts.
  • Achieved a measurement sensitivity of 7.664 nm/N with a hollow PMMA microsphere.
  • Successfully determined force magnitude using various microsphere materials and structures.

Conclusions:

  • The WGM shift in dielectric microspheres is a viable principle for micro-optical force sensing.
  • Hollow PMMA microspheres offer high sensitivity for force detection.
  • This sensor concept shows potential for precise force measurement applications.
