摘要:
The present invention is a nitride compound semiconductor laser, in which a cleaved end face is flat, and a breakdown of a laser end face induced during an operation can be suppressed, which consequently enables a life to be prolonged. In the nitride compound semiconductor laser, a stress concentration suppression layer is formed between an active layer and a cap layer.
