| Research Abstract |
In order to clarify the mechanism of gradual degradation of optical devices, degree of degradation under optical irradiation was evaluated for materials for next generation optical devices and quantum dot structure. It was clarified that striking degradation phenomenon is observed in GaInNAs. However, no definite degradation phenomena have been confirmed for InGaN and AlInGaAs. The InAs quantum dot structure did not show any degradation under comparatively strong optical irradiation. It is required to carry out the similar experiment for practical device structures.
