Abstract

Optical amplifiers based on semiconductor laser-like structures are attracting increasing attention for application in lightwave systems. To achieve low gain ripple in a traveling-wave amplifier, the facet reflectivity must be very low, placing stringent tolerance requirements on the facet coating. As an alternative to facet coating, it has been proposed that a low reflectivity could be achieved by combining a less critical coating with an angled facet.1
