We demonstrate a giant polarization splitting of the emission of a high quality monolithic microcavity with an embedded ultrathin organic tetrakis(4-methoxyphenyl)porphyrin layer. The usual employed mechanism, based on the mismatch between the center of the mirror stopband and the wavelength of the microcavity, accounts only for a small fraction of the observed splitting. Optical and atomic force microscopy measurements allowed us to attribute it to local crystalline molecular order. This opens the way for the design and optimization of highly polarized compact optical sources.

Abstract
We demonstrate a giant polarization splitting of the emission of a high quality monolithic microcavity with an embedded ultrathin organic tetrakis(4-methoxyphenyl)porphyrin layer. The usual employed mechanism, based on the mismatch between the center of the mirror stopband and the wavelength of the microcavity, accounts only for a small fraction of the observed splitting. Optical and atomic force microscopy measurements allowed us to attribute it to local crystalline molecular order. This opens the way for the design and optimization of highly polarized compact optical sources.File in questo prodotto:
