  • Abstract
    The monolithic integration of an index-guided single lateral mode optical preamplifier with a power tapered semiconductor laser amplifier is reported. With a coupled input power of only 6 mW, 4.5 W of output power is obtained at 810 nm. The far-field pattern is dominated by a diffraction-limited single lobe. An internal small signal gain of 35 dB is demonstrated.
