Abstract: With the aid of multi-step trials,the active monitoring method adopted to control the deposition of the AR coatings on the facets of the semiconductor lasers has been optimized.As a result,a travelling-wave semiconductor amplifier with an average facet reflectivity of less than 3×10-4 has been obtained,and 20dB signal gain at 1.3μm has been observed.
