Theoretical analysis for effect of facet reflections on amplification and noise characteristics in semiconductor optical amplifier

In most cases, the semiconductor optical amplifiers (SOA) are used with anti-reflection coating for its facets to avoid laser oscillation. Providing effects by residual reflection at the facets are theoretically analyzed. When the reflection by the back facet exists, the SOA shows larger amount of t...
