The influence of the reflection coefficient of cleaved facets from a double heterostructure laser on the 1/f noise in light output is investigated. The experimental noise results are obtained by partially embedding the laser in Canada balsam, resulting in a decrease of the reflection coefficient and by evaporating an aluminum coating which results in a fully reflecting facet. These experimental results are shown to be in full agreement with an extension of existing models proposed by Fronen and Vandamme. The authors also calculated the 1/f noise arising from fluctuations in the refractive index as suggested by Kiss and conclude that this noise is negligible compared to the bulk noise in semiconductor lasers.
