Angle-resolved Reflectivity and Transmissivity of a TE-polarized Wave Incident On a Microcavity Containing Strongly Coupled In-plane Oriented 1D Excitons

TL;DR

This paper investigates the optical properties of a microcavity with strongly coupled, in-plane oriented 1D excitons, analyzing how TE-polarized waves are reflected and transmitted, supported by a theoretical model and experimental data.

Contribution

It introduces a simple model for TE wave propagation in microcavities with oriented 1D excitons and compares it with experimental measurements on liquid-crystalline PFO layers.

Findings

Reflected and transmitted fields are superpositions of photons leaking parallel and perpendicular to exciton orientation.

The model successfully explains the propagation of TE-polarized waves in such microcavities.

Experimental results align with the theoretical predictions.

Abstract

Here we report on the reflectivity and transmissivity of a TE-polarized wave incident on a microcavity containing strongly coupled, in-plane oriented one dimensional (1D) excitons. We first discuss the propagation of the electric field through the cavity and present a simple model which allows us to understand the underlying physics. We then compare this model to previous reports and perform our own measurements on a microcavity containing an oriented layer of liquid-crystalline poly(9,9-dioctyfluorene) (PFO). We show that in all cases, the reflected and transmitted electric fields are the superpositions of photons leaking parallel and perpendicular to the excitons' orientation.
