Effect of excess Zn around the active‐stripe mesa on the lasing threshold current of a [01̄1] oriented InGaAsP/InP buried‐heterostructure laser diode

Autor: D. L. Coblentz, A. M. Sergant, R. A. Logan, Sung-Nee George Chu

Publikováno v: Applied Physics Letters. 65:2377-2379

Buried‐heterostructure lasers with current confinement by reverse biased junctions always demonstrate poor performance when oriented along the [011] direction of a (100)InP substrate in comparison to the same structure oriented along the [011] dire

Publikováno v: Applied Physics Letters. 63:1886-1888

Grating irregularities in distributed feedback (DFB) laser structures form strong light scattering centers during lasing operation. The existence of such scattering centers may possibly affect the laser reliability. We report an elimination of the li
