Carrier Generation and Recombination

1.3K
Carrier generation is the process by which electron-hole pairs (EHPs) are created within the semiconductor. In direct-bandgap semiconductors, such as gallium arsenide (GaAs), this occurs efficiently when energy absorption prompts valence electrons to leap into the conduction band, leaving behind holes.
This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
Indirect generation involves an...

Photoluminescence: Fluorescence and Phosphorescence

4.0K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Area of Science:

  • Quantum Optics
  • Laser Physics
  • Non-linear Optics

Background:

  • Vertical-Cavity Surface-Emitting Lasers (VCSELs) are potential sources for quantum information applications.
  • Four-wave mixing (FWM) is a non-linear optical process capable of generating entangled photon pairs.

Purpose of the Study:

  • To investigate the feasibility of generating photon pairs via degenerate FWM in a resonant VCSEL.
  • To analyze the impact of cavity dispersion on photon pair generation rates.
  • To identify optimal VCSEL characteristics for efficient photon pair production.

Main Methods:

  • Utilized quantum optics methods to model the FWM process within a VCSEL cavity.
  • Calculated the two-photon production rate, photon spectrum, and signal-idler cross-correlations.
  • Considered a standard Gallium Arsenide (GaAs) medium within the VCSEL.

Main Results:

  • Demonstrated that resonant FWM in VCSELs can generate signal and idler photon pairs.
  • Showed that the dispersion of the GaAs medium significantly diminishes the two-photon production rate.
  • Quantified the reduction in photon pair generation due to cavity dispersion effects.

Conclusions:

  • VCSELs are feasible for photon pair generation, but dispersion poses a significant challenge.
  • Specific VCSEL designs minimizing dispersion are required for efficient quantum light sources.
  • Results provide guidance for engineering VCSELs tailored for quantum optics applications.
