The formation of long-lived high-correlated states of light and polarization in high-quality semiconductor microcavity at the resonant laser excitation

TL;DR

This paper investigates long-lived high-correlation states of light and polarization in a high-quality semiconductor microcavity under resonant laser excitation, revealing oscillations not caused by weak Rabi interactions but linked to spectral properties.

Contribution

It demonstrates the formation of long-lived correlated states in microcavities and clarifies their origin beyond weak Rabi coupling, based on spectral resonance conditions.

Findings

Oscillations in correlation functions last nanoseconds.

Oscillations are not due to weak Rabi interaction.

Resonance with microcavity spectral components causes oscillations.

Abstract

The correlation function of radiation from a high-quality semiconductor microcavity at the resonant laser excitation demonstrates oscillations with surprisingly long-period and damping times of a nanosecond range. It was shown that the oscillations are not attributed to weak Rabi interaction between long-lived exciton states and intracavity electromagnetic field. The study of a response with high spectral resolution had revealed that the oscillations arise if a spectral position as well as a period of longitudinal laser modes is similar to modulation components of a microcavity transmission spectrum.
