This letter describes the fabrication of a multiple quantum well GrinSch traveling wave-type amplifier combined with a tapered waveguide and a window region to reduce optical reflection at both end facets. Optical fiber-to-fiber gain of 10.4 dB (signal gain of 24.4 dB) under gain variation below 1.0 dB is demonstrated in the 1.55 μm wavelength region.
