Abstract :
We report a 0.98-μm wavelength tapered broad-area InGaAs QW laser amplifier with a monolithically integrated waveguide lens. CW operation with 1 W output was measured with 10 mW input from a 0.98 μm diode laser. The amplifier output is focused to a single spot by the integrated waveguide lens
