Abstract

The results of studying a GaAs-based laser with InGaAs waveguide quantum wells, which operates at room temperature in the electric-pumping mode, are presented. The minimal generation threshold is 15 A. Stable lasing at a wavelength of 1010 nm is attained, and the width of the radiation pattern in the plane perpendicular to the structure layers is (10 ± 2)°.
