| 英文摘要 | We have discovered that the yield of DFB lasers (10) suitable, e.g., for use in AM CATV systems (30) can be substantially increased if the lasers have a back facet (16) with a higher reflectivity (>80%, preferably >90%) HR coating (18) thereon than is conventional (e.g., ∼65%). Exemplary currently preferred embodiments of the invention comprise a three-pair stack of λ/4 yttrium-stablized zirconia/Si having about 95% reflectivity. |
