| Abstract: | 1.3 μm semiconductor optical amplifier (SOA) with angled facets has been studied. Because of the angled facets, the overlap of the reflective light and the guided mode is reduced, which causes the reduction of the effective reflectivity. After antireflective (AR) coating, less than 10-4 reflectivity has been realized, and 25 dB gain of the SOA with a 400 μm cavity length has been obtained. |
| Keywords: | tilted cavity antireflective coating gain semiconductor optical amplifier |
