We describe the fabrication and characteristics of a DFB laser monolithically integrated with an optical traveling-wave amplifier prepared using OMVPE/LPE hybrid growth. A unique feature is its 7°-tilted end facets formed by reactive ion etching for reduction of optical crosstalk. Owing to the low reflectivity of the facets, the elemental devices operate with little interference.
