Standing Waves in a Cavity01:28

Standing Waves in a Cavity

1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Area of Science:

  • Non-equilibrium physics
  • Quantum optics
  • Condensed matter theory

Background:

  • Driven-dissipative optical microcavities are key for studying non-equilibrium dynamics.
  • The Kibble-Zurek mechanism explains non-equilibrium phase transitions, but critical dynamics in microlasers, especially first-order transitions in non-Hermitian systems, are understudied.

Purpose of the Study:

  • Investigate the temporal critical behavior of lasing-state transitions in an ultrahigh-Q whispering-gallery microlaser.
  • Characterize the dynamics of switching between supermodes by dynamically ramping non-Hermitian coupling.
  • Determine the transition time as a function of ramp speed and explore its universality.

Main Methods:

  • Utilized an ultrahigh-Q whispering-gallery microlaser.
  • Dynamically ramped non-Hermitian interferometric coupling to induce state switching.
  • Employed high-resolution radio-frequency beat-note readout to capture real-time switching dynamics.

Main Results:

  • Observed direct real-time switching between two nearly degenerate standing-wave supermodes with opposite parities.
  • Measured transition times and found a power-law scaling with an exponent of approximately 0.5.
  • Demonstrated the robustness of this power-law scaling in coupled-cavity laser networks.

Conclusions:

  • The study reveals a fundamental speed limit for microcavity laser state conversion.
  • The observed power-law scaling provides insights into critical dynamics of first-order phase transitions in non-Hermitian systems.
  • Findings are relevant for understanding and controlling non-equilibrium phenomena in quantum optical systems.
