## TL;DR

This paper develops a theoretical model for polariton-mediated Raman scattering in semiconductor microcavities, accurately predicting experimental Raman intensities by incorporating nonperturbative exciton-photon coupling and lifetime effects.

## Contribution

It introduces a comprehensive nonperturbative approach to calculate Raman scattering intensities, including lifetime effects and photon-electron-hole continuum coupling, aligning well with experimental data.

## Key findings

- Excellent agreement with experimental Raman intensities
- Effective modeling of exciton-photon coupling and lifetime effects
- Predicts Raman scattering resonances in microcavities

## Abstract

We calculate the intensity of the polariton mediated inelastic light scattering in semiconductor microcavities. We treat the exciton-photon coupling nonperturbatively and incorporate lifetime effects in both excitons and photons, and a coupling of the photons to the electron-hole continuum. Taking the matrix elements as fitting parameters, the results are in excellent agreement with measured Raman intensities due to optical phonons resonant with the upper polariton branches in II-VI microcavities with embedded CdTe quantum wells.
