Standing Waves in a Cavity01:28

Standing Waves in a Cavity

1.2K
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:

  • Optics and Photonics
  • Materials Science
  • Semiconductor Physics

Background:

  • Microlasers rely on whispering gallery modes for light emission, achieving high Q-factors through total internal reflection.
  • Integration of microlasers is facilitated by light emission predominantly occurring in the plane of the structure.

  • To explore the fabrication of microlasers on silicon substrates using III-V heterostructures.

Main Methods:

  • Utilizing whispering gallery modes for spectral determination in microlasers.
  • Employing In(Ga)As quantum dots to suppress non-radiative recombination via deep carrier localization.
  • Fabricating microdisk lasers using conventional epitaxial structures and post-growth processing.
  • Growing III-V heterostructures on silicon substrates.

Main Results:

  • Achieved high Q-factor microlasers due to total internal reflection.
