Influence of orientation dependent growth kinetics on the performance of InGaAsP buried crescent lasers

Abstract

The growth reproducibility of the separate optical confinement buried crescent laser has been studied in the wavelength region of 1.3<λ≤1.62 μm. The performance and yield of λ=1.55 μm lasers were found to be impaired by the competition between the (100) and (111) growth habits leading to the perturbed growth of the active layer. These results are discussed in terms of the crystallographic direction dependence of the liquid-solid distribution coefficient.
