Semiconductor laser provided with means of reinjecting the spontaneous emission into the active layer |
摘要 |
Double hetero-structure semiconductor laser in which the contact layer 22 is transparent to the spontaneous radiation emitted by the active layer 18. The light directed upwards is then reflected by the metallic layer 24 and returned to the active layer 18. Application to optical telecommunications. <IMAGE> |
