摘要
III thiS paper we study theoretically the characteristics of a GaAs-AlGaAs laser transverse optical cavity with a parabolic graded variation of the refractive index (GRIN-SCH). We give an exact solution of the wave equation and analyze the near field distribution as well as the values of the effective refactive index of the fundamental mode. The condition for a mono mode optical cavity are also deduced. The behavior of the confinement factor and the far field in the plane perpendicular to the active region are reported. The results for the GRIN-SCH structure are compared with a similar SCH-straight laser transverse optical cavity.
