Abstract :
Structure in the far-field pattern of current-confined stripe-geometry double-heterostructure lasers in the angle range \\pm 20\\deg is observed at current levels of less than frac{1}{4} of threshold value. The behavior is explained by leaky-mode guiding due to a gain maximum under the stripe and to a negative refractive index step on the order of -0.01.
