AlGaInAs lasers are suitable for element devices of optical communication systems. However, degradations in forward-biased ESD tests and accelerated aging tests were found. Since both degradations occurred at the facet of the laser, we improved facet-coating processes. In forward-biased ESD tests, we introduced a passivation of an Al ultrathin layer just before facet-coating. The Al ultrathin layer prevents oxidation of the facet from oxygen atmosphere. The degradation ratio of 1 kV ESD tests was decreased from 40% to 0% by introducing the passivation. In accelerated aging tests of 200 mA at 85℃, we introduced facet-coating with compressive strain. This degradation differed completely from that caused by ESD; dislocation loops covered the entire active layer at the facet. The degradation ratio of 800 h aging was decreased from 5% to 0% by introducing the compressively strained facet-coating. |
