Suppression of output nonlinearities in doublehyphen;heterostructure lasers by use of misaligned mirrors

摘要

Nonlinearity (kinks) in the dependence of light output power on current has been effectively eliminated by the use of mirrors aligned at a small angle from the direction perpendicular to the stripe or filament. Such a structure increases confinement of the lasing filament and causes an increase in threshold current density that is smaller than that produced by stripe narrowing.
