Area of Science:

  • Optics and Photonics
  • Condensed Matter Physics
  • Semiconductor Physics

Background:

  • Semiconductor microcavities exhibit intrinsic disorder, leading to multiple light scattering and static speckle.
  • Understanding light propagation in disordered systems is crucial for optical device applications.

Purpose of the Study:

  • To investigate the phenomenon of weak localization of light within a semiconductor microcavity.
  • To analyze the effects of intrinsic disorder on light scattering and coherence.
  • To confirm the presence of a coherent backscattering cone and its characteristics.

Main Methods:

  • Experimental observation of light scattering in a semiconductor microcavity.
  • Statistical analysis by averaging over multiple realizations of the microcavity disorder.

  • Characterization of the backscattered light pattern and enhancement factor.

    • Main Results:

    • Demonstrated weak localization of light in the semiconductor microcavity.
    • Observed a coherent backscattering cone with an enhancement factor greater than or equal to 2, consistent with reciprocity.
    • The coherent backscattering cone manifested as a ring-shaped pattern due to microcavity confinement.

    Conclusions:

    • Intrinsic disorder in semiconductor microcavities facilitates weak localization of light.
    • Coherent backscattering is a measurable phenomenon in these systems, obeying fundamental optical principles.
    • Microcavity geometry influences the spatial distribution of coherent backscattering.
