Optical field distribution and spectral property of GaAs/GaAlAs semiconductor laser arrays

In this paper, we present experimental results of GaAs/GaAlAs laser arrays with linearly varied stripe widths. Near-diffraction-limited, single-lobed far field pattern and single longitudinal mode emission spectra are obtained. Experimental results are compared between uniform and nonuniform stripe widths. Furthermore, the spectral properties are discussed qualitatively.
