Bragg soliton polarization evolution

Nonlinear propagation of optical pulses in fiber Bragg gratings is studied experimentally and with numerical simulations of the coupled mode equations. After a review of enhanced nonlinear interactions for pulse wavelengths near the short wavelength edge of the photonic bandgap associated with the grating, this study explores polarization evolution during nonlinear pulse propagation. Initial results for polarization instabilities and expectations for vector Bragg solitons are described.

Efficiency enhancements of microcavity organic light-emitting diodes

We report microcavity efficiency enhancement of organic electroluminescent devices based on the hole transporter bis(triphenyl)diamine and the electron transporter and light emitter tris(8-hydroxyquinoline)aluminum. Microcavity organic light emitting diodes are described which emit 4 times the light measured in the forward direction, or almost twice the total light of a non-cavity organic light-emitting diode for identical electrical drive conditions.
